Print the information about the nonzero group counts at each lambda step in the HDtweedie
object. The result is a two-column matrix with columns Df
and Lambda
. The Df
column is the number of the groups that have nonzero within-group coefficients, the Lambda
column is the the corresponding lambda.
a two-column matrix, the first columns is the number of nonzero group counts and the second column is Lambda
.
