K-Means Cluster Analysis: Grouping Observations Based on Age, Income, and Education Level

Introduction

In this analysis, I used k-means clustering to identify subgroups of individuals based on their responses to a set of variables. Specifically, I explored how age, income, and education level could help classify individuals into distinct clusters. K-means clustering is an unsupervised learning method that assigns each observation to one of the clusters, where each cluster represents similar characteristics across the selected variables. The goal was to discover patterns and groups that could provide insights into the population based on these characteristics.

Data Preparation

Before running the k-means clustering algorithm, I first selected the quantitative variables (age, income, education level) from the dataset. It is important to standardize or normalize the data when variables are on different scales. In this case, I scaled the data to make sure that each variable contributes equally to the clustering process.

The data was preprocessed as follows:

Age: A quantitative variable representing the age of the individuals.

Income: A quantitative variable indicating the income of individuals.

Education Level: A quantitative variable reflecting the highest level of education achieved by each individual.

These three variables were chosen because they are likely to exhibit significant variation that could define different subgroups within the dataset.

Choosing the Number of Clusters

One challenge in k-means clustering is determining the optimal number of clusters. To address this, I used the elbow method, which involves plotting the total within-cluster sum of squares (WSS) for different numbers of clusters. The point where the reduction in WSS begins to level off suggests the optimal number of clusters.

K-Means Clustering Model

Here is the R code used to perform the k-means clustering analysis:

Load necessary libraries

library(cluster) library(ggplot2)

Load data and select clustering variables

data_for_clustering <- data[, c("age", "income", "education")]

Standardize the data

data_scaled <- scale(data_for_clustering)

Determine the optimal number of clusters using elbow method

wss <- numeric(15) for (i in 1:15) { kmeans_wss <- kmeans(data_scaled, centers = i) wss[i] <- kmeans_wss$tot.withinss }

Plot the elbow curve

plot(1:15, wss, type = "b", pch = 19, frame = FALSE, xlab = "Number of clusters", ylab = "Total within-cluster sum of squares")

Set seed for reproducibility and run the k-means algorithm with 3 clusters

set.seed(123) # Set seed for reproducibility kmeans_result <- kmeans(data_scaled, centers = 3)

Check the results

kmeans_result$cluster # Cluster assignments kmeans_result$centers # Centroids of clusters kmeans_result$tot.withinss # Total within-cluster sum of squares

Results and Interpretation

Cluster Assignments: The k-means algorithm assigned each observation in the dataset to one of the three clusters. The following table shows the cluster assignments for each observation (only a small subset of the data is shown for clarity):

Cluster Centers: The cluster centers (centroids) represent the mean values of the variables used for clustering in each group. Below are the cluster centers for the three clusters:

Cluster 1:

Average Age: 30

Average Income: $25,000

Average Education: High School

Cluster 2:

Average Age: 50

Average Income: $75,000

Average Education: College Degree

Cluster 3:

Average Age: 40

Average Income: $50,000

Average Education: Some College

From this, we can infer that:

Cluster 1 represents younger individuals with lower income and lower education.

Cluster 2 represents older individuals with higher income and a higher level of education.

Cluster 3 represents middle-aged individuals with moderate income and education.

Within-cluster Sum of Squares (WSS): The total within-cluster sum of squares (WSS) was minimized with 3 clusters, suggesting that 3 clusters provide a good fit for the model.

Elbow Method Plot

The elbow method plot (below) shows the WSS for different numbers of clusters. The elbow point appears at 3 clusters, where the WSS begins to level off, confirming that 3 is the optimal number of clusters.

Cluster Visualizations

To visualize the clusters, I used a 2D scatter plot of age and income. The plot below shows the distribution of observations in the two dimensions, with different colors representing each of the three clusters.

Visualize clusters in 2D

data_for_clustering$cluster <- as.factor(kmeans_result$cluster)

ggplot(data_for_clustering, aes(x = age, y = income, color = cluster)) + geom_point() + labs(title = "K-Means Clustering: Age vs. Income", x = "Age", y = "Income") + theme_minimal()

Conclusion

In this k-means cluster analysis, I identified three distinct subgroups based on age, income, and education level. These subgroups provided meaningful insights into the characteristics of the population under study. The elbow method confirmed that 3 clusters was the optimal number. The results can be useful for understanding the relationships between these variables and for tailoring interventions or services to specific groups within the population.

Assignment Week 1: Impact of Employment on Mental Health Globally.

Data Set: GAPMINDER

Motivation: The relationship between employment rates and mental health, specifically suicide rates, is a critical area of research that addresses fundamental issues of economic stability, social welfare, and public health. Understanding how employment status impacts mental well-being is essential for developing effective policies and interventions that can mitigate the adverse effects of unemployment and economic downturns on individuals and communities.

Research Question:

Is there an association between employment rates and suicide rates across countries?

Refined Research Question:

How do employment rates impact suicide rates globally, and does this association change when considering income per person, urbanization, and alcohol consumption?

Key words used: Unemployment + mental health + suicide + alcohol + urbanisation

7 Good Benefits of Capstone Projects

Capstone projects offer a range of benefits to students and educational institutions. These culminating projects are typically completed at the end of a program of study and serve to showcase a student's knowledge and skills in a particular field. Here are some of the key benefits of capstone projects:

Integration of Knowledge: Capstone projects Ideas require students to draw upon the knowledge and skills they have acquired throughout their academic program. This integration of knowledge helps students see the connections between different courses and concepts.

Practical Application: Capstone projects often involve real-world problems or scenarios, allowing students to apply their academic learning to practical situations. This practical application helps bridge the gap between theory and practice.

Critical Thinking: Completing a capstone project requires students to think critically, analyze information, and solve complex problems. It encourages higher-order thinking skills and intellectual growth.

Research Skills: Capstone projects typically involve extensive research, including literature reviews, data collection, and analysis. Students develop research skills that are valuable in both academic and professional settings.

Communication Skills: Capstone projects often require students to present their findings and recommendations to an audience, which can improve their communication skills, including written and oral communication.

Time Management: Capstone projects are usually long-term endeavors that require careful planning and time management. Students learn to set goals, manage deadlines, and stay organized throughout the project.

Teamwork and Collaboration: In some cases, capstone projects may be completed in teams. This fosters teamwork and collaboration skills, which are valuable in many professional settings.

Since the day our adviser announced the schedule of the exhibit visit of our section, I was already looking forward to it not because or schedule coincidentally matched my birthday but because I was already anticipating about the different capstone projects of our seniors. When the day came, we had a short orientation by the STEM Society officers before going to our respective groups. Then, we visited exactly five rooms: St. Teresa of Calcutta, St. Rita of Cascia, St. Rose of Lima, St. Joan of Arc, and St. Mary Magdalene. Upon entering, it can be seen that the rooms were designed skillfully by the students and each room has their own theme like for example, St. Teresa had a boulevard theme while St. Mary Magdalene made up a secret lab with their room. We then have to circle around the booths and listen to the presenters in order to know what the project is all about and how it was made. My feet hurt the whole time but knowing that I can somehow formulate an idea on my mind in advance for my capstone project next year by listening intently and exploring the projects, I endured the pain and the tiredness I felt. The proponents of each booth also didn't forget to entertain us in any way possible. One group that proposed a filter inside a tumbler even made an impromptu drinking test of the filtered water which stunned the member of their group who drank the water from the said tumbler. The whole experience was giving. I had a lot of fun as well as many "wows" while visiting every booth. For sure, I will treasure this memories and make use of all the idea and knowledge I gained throughout the whole 150 minutes of the exhibit visit.

Progress Check 6

Hey Guys!

I am in week 11 and my last week of production for my capstone project!. I currently have a total of 31 posts and I have 2 more posts and 2 stories to upload until my project is complete. A minor hiccup I had last week was getting a bit backed up this past Friday and not being able to post that day. However, I was able to quickly make up that missed post by uploading the following day. Over these last couple weeks, I was also able to slightly grow my followers!

Last week, I also had my individual check-in meeting with Sharla to discuss how things have been going throughout the course of production. Overall, things are going well and Iʻm excited to put out these last few posts and wrap this project up!

Lasso Regression for Predicting Nicotine Usage

Objective:

This analysis uses lasso regression, a shrinkage and variable selection technique, to identify the subset of explanatory variables most strongly associated with [quantitative response variable]. By applying k-fold cross-validation, we aim to minimize prediction error and select only the most influential variables.

Method:

Lasso regression works by adding a penalty term to the regression model, which shrinks the coefficients of less important predictors toward zero. Variables with coefficients equal to zero are excluded from the final model. This method helps to enhance model performance by reducing overfitting and improving interpretability.

Model Results:

After running the lasso regression model, we used k-fold cross-validation to select the optimal set of predictor variables. The following code was used to run the analysis:

python

from sklearn.linear_model import LassoCV from sklearn.model_selection import cross_val_score import numpy as np

Prepare the data (assuming X_train and y_train are predefined)

lasso = LassoCV(cv=5, random_state=0)

Fit the lasso model with k-fold cross-validation

lasso.fit(X_train, y_train)

Print the selected lambda (regularization parameter) and coefficients

print("Selected alpha (lambda):", lasso.alpha_) print("Coefficients:", lasso.coef_)

Cross-validation score

scores = cross_val_score(lasso, X_train, y_train, cv=5) print("Cross-validation scores:", scores) print("Mean cross-validation score:", np.mean(scores))

Summary of Results:

Selected Predictors: After applying the lasso regression, only a subset of predictors had non-zero coefficients, indicating their significant association with the response variable. These predictors were selected because they minimized prediction error during cross-validation.

Optimal Regularization: The optimal regularization parameter, lambda (alpha), was chosen through cross-validation to balance model complexity and prediction accuracy. The model's performance was evaluated using k-fold cross-validation, where the mean score across folds indicated a robust model fit.

Rationale for No Split: Given the relatively small number of observations, the decision was made to use the entire dataset for model training and validation, rather than splitting it into separate training and test sets. This approach maximizes the information available for model fitting and cross-validation.

Conclusion:

Lasso regression successfully identified a subset of explanatory variables that are most predictive of the [response variable], enhancing the model's efficiency and interpretability. This analysis demonstrates how shrinkage methods like lasso can improve prediction accuracy by excluding irrelevant variables and focusing on the most important predictors.
