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

Compute the observed ordinal mean and cov in a row

Description

Estimate the conditional mean and cov at observed ordinal entries through sampling

Usage

est_z_row_ord(
  z,
  lower,
  upper,
  sigma_oo,
  ord_indices = NULL,
  obs_indices = NULL,
  ord_obs_indices = NULL,
  obs_in_ord = NULL,
  ord_in_obs = NULL,
  n_sample = 5000
)

Arguments

z	A row of Z
lower	A row of Lower
upper	A row of Upper
sigma_oo	Sigma_{obs, obs}
ord_indices	Boolean vector where TRUE indicates ordinal entries.
obs_indices	Boolean vector where TRUE indicates observed entries.
ord_obs_indices	Boolean vector where TRUE indicates observed ordinal entries.
obs_in_ord	Boolean vector where TRUE indicates observed ordinal entries.
ord_in_obs	Boolean vector where TRUE indicates ordinal entries.
n_sample	Number of MC samples, only used when trunc_method is 'Sampling'

Value

A list containing
