Assignment 6 Q1

Heinsbroek Lab R practice

Ficha técnica de la tortuga juvenil de la especie Chelonia mydas monitoreada por el CEA en la bahía de Akumal durante 2024-2025.

This assignment applies three modern regression techniques—Ridge, LASSO, and Partial Least Squares (PLS)—to a real dataset with 10+ predictors and a continuous outcome. You will review the core ideas and formulas behind each method, then use R to fit the models, tune hyper-parameters via cross-validation, and generate coefficient tables, selection metrics (e.g., RMSE, MAE, R²), and diagnostic plots. The analysis compares which variables LASSO retains or removes, how Ridge and PLS address multicollinearity differently, and which approach yields the strongest predictive performance.
