Prostate

These data come from a study that examined the correlation between the
 level of prostate specific antigen and a number of clinical measures
 in men who were about to receive a radical prostatectomy. It is data
 frame with 97 rows and 9 columns.

datasets

An implementation of the induced smoothing (IS) idea to lasso regularization models to allow estimation and inference on the model coefficients (currently hypothesis testing only). Linear, logistic, Poisson and gamma regressions with several link functions are implemented. The algorithm is described in the original paper; see <doi:10.1177/0962280219842890> and discussed in a tutorial <doi:10.13140/RG.2.2.16360.11521>.
