Check if glmnet should call cox.path
Helper function to check if glmnet() should call cox.path().
use.cox.path(x, y)
x |
Design matrix. |
y |
Response variable. |
For family="cox", we only call the original coxnet() function if
(i) x is not sparse, (ii) y is right-censored data, and (iii) we are
not fitting a stratified Cox model. This function also throws an error
if y has a "strata" attribute but is not of type "stratifySurv".
TRUE if cox.path() should be called, FALSE otherwise.
