Very simple to use. The main fitting function clogitL1 accepts x, y data and a strata vector indicating stratum membership. It fits the exact conditional logistic regression model at a grid of regularisation parameters. Only 7 functions:

• clogitL1

• cv.clogitL1

• plot.clogitL1

• plot.cv.clogitL1

• print.clogitL1

• summary.clogitL1

• summary.cv.clogitL1
