Shrinkage Regression


shrinkage and regression to the mean - J B Copas, 1997

The extent of this shrinkage is studied for multiple and logistic regression models, and is found to be related to simple goodness-of-fit statistics of the ...

Penalized or shrinkage models (ridge, lasso and elastic net) - DataSklr

Shrinkage means that the coefficients are reduced towards zero compared to the OLS parameter estimates. This is called regularization.
