Objective: Investigate how individual and regional factors jointly influence participants' Income by employing multilevel modeling. Assumption: Assume that participants are nested within different Geographical Regions, and that there may be regional-level effects on Income. Tasks: 1. Data Preprocessing: . Load the statsnew.csv dataset. . Check for missing values and handle them appropriately. Convert categorical variables into suitable numerical formats. Explore the distribution of Income across different Geographical Region S. 2. Exploratory Data Analysis: Visualize the relationship between Income and key predictors (EducationLevel, EmploymentStatus, Age, HoursWorked, etc.). Examine intra-class correlation (ICC) to assess the necessity of a multilevel approach. 3. Model Building: • Specify a two-level hierarchical linear model with Income as the dependent variable. Level 1 (Individual Level): Predictors such as Age, EducationLevel, EmploymentStatus, HoursWorked, JobSatisfaction, etc. Level 2 (Regional Level): Predictors such as average AccessToHealthcare, regional School Funding, or other region-specific variables if available. Include random intercepts for Geographical Region to account for regional variability. 4. Model Diagnostics: • Assess model assumptions, including normality of residuals and homoscedasticity. Evaluate the significance of random effects using likelihood ratio tests. 5. Model Comparison: Compare the multilevel model with a standard linear regression model to determine the added value of the hierarchical approach. Use information criteria (AIC, BIC) and goodness-of-fit measures for comparison.
