• Ensure diagnostic checks (multicollinearity, residual analysis, heteroscedasticity, model fit KPIs).

3. Classification & Machine Learning

• Develop classification models (Random Forests, XGBoost, SVM, Gradient Boosting, Neural Networks).
• Perform model training, validation, hyperparameter tuning, and crossvalidation.
• Build endtoend ML pipelines including data preprocessing, feature engineering, and model deployment.

4. Data Management & Analytics
