Description
Principal Components Lasso.
Description
A method for fitting the entire regularization path of the principal components lasso for linear and logistic regression models. The algorithm uses cyclic coordinate descent in a path-wise fashion. See URL below for more information on the algorithm. See Tay, K., Friedman, J. ,Tibshirani, R., (2014) 'Principal component-guided sparse regression' <arXiv:1810.04651>.

Bug fixes:
predict.pcLassonow works whenfamily = “binomial”(previously, the intercept term was being added in an incorrect manner).- Previously,
standardize = TRUEscaled thebetacoefficients and intercepta0incorrectly. This has been fixed. pcLassonow generates lambda values for the objective function RSS/(2n) + penalty, instead of that for RSS/2 + penalty.
