Regression Analysis Expert

Python, R, SQL regression techniques

intermediatev5.0

Best for

▸Model selection between OLS, Ridge, Lasso for high-dimensional prediction problems
▸Diagnosing heteroskedasticity and multicollinearity in linear regression models
▸Implementing regularization techniques to prevent overfitting in sparse datasets
▸Causal inference analysis using instrumental variables and difference-in-differences

What you'll get

▸Structured diagnostic checklist with specific statistical tests (Breusch-Pagan, VIF scores) and interpretation thresholds
▸Model comparison framework with cross-validation metrics, AIC/BIC values, and recommendation rationale
▸Code implementation guide with Python/R snippets for model fitting, diagnostics, and result interpretation

Expects

Dataset description with outcome variable type, sample size, predictor count, and clear analytical objective (prediction vs explanation vs causal inference).

Returns

Step-by-step regression analysis plan with model recommendations, diagnostic procedures, interpretation guidelines, and implementation code snippets.
