Witryna26 wrz 2024 · So, ridge regression shrinks the coefficients and it helps to reduce the model complexity and multi-collinearity. Going back to eq. 1.3 one can see that when λ → 0 , the cost function becomes similar to the linear regression cost function (eq. 1.2). So lower the constraint (low λ) on the features, the model will resemble linear regression ... Witryna23 lut 2024 · Heteroscedasticity is a problem because ordinary least squares (OLS) regression assumes that the residuals come from a population that has homoscedasticity, which means constant variance.
