impute_init: Return a complete Z matrix based on SVD initialization

In udellgroup/mixedgcImp: Missing value imputation for mixed data through Gaussian copula

Return a complete Z matrix based on SVD initialization

Description

The SVD initialization is based on a complete Z matrix with missing entries filled in by zero. Useful for getting initial estimates of copula parameters

Usage

impute_init(Z, rank, Lower, Upper, d_index)

Arguments

rank	the number of latent factors
Z_meanimp	Initial complete Z with mean (i.e. zero) imputation
r_lower	Lower boundary of truncated intervals for ordinal columns
r_upper	Upper boundary of truncated intervals for ordinal columns

Value
