family

A family object, typically returned by esvd_family()

s

The library size vector, [n x 1]

gamma

The nuisance parameter vector, [p x 1]

l2peny

The l2 penalty parameter for Y, a scalar

l2penz

The l2 penalty parameter for Z, a scalar

verbose

Verbosity parameter

inplace

Whether the input XC_init will be modified and returned
