RXshrink: Maximum Likelihood Shrinkage using Generalized Ridge or Least Angle Regression Methods

Functions are provided to calculate and display ridge TRACEs for various shrinkage PATHS. They determine the m-Extent of shrinkage most likely, under Normal-distribution theory, to produce biased estimates of regression (beta) coefficients with minimum MSE Risk. An alternative function, correct.signs(), provides beta coefficient estimates when an ill-conditioned (nearly multicollinear) model yields OLS estimates with ("wrong") numerical signs that disagree with the signs of the observed correlations between the Y-outcome and the selected X-predictor variables.
