WebJul 8, 2024 · I am dealing with Regression models (Ordinary Least square, Huber Regression, MM Estimator, and Ridge Regression). I would like to check which model is more robust to outliers and multicollinearity ... If you have outliers in your data then it is sensible to use a robust measure, since non-robust measures might give you very … WebLesson 13 Objectives Upon completion of this lesson, you should be able to: Explain the idea behind weighted least squares. Apply weighted least squares to regression examples with nonconstant variance. Apply logistic regression techniques to datasets with a binary response variable.
