Istep_Z: I-step of LUCID

In LUCIDus: LUCID with Multiple Omics Data

I-step of LUCID

Description

Impute missing data in Z by maximizing the likelihood given fixed parameters of LUCID

Usage

Istep_Z(Z, p, mu, sigma, index, lucid_model)

Arguments

Z	an N by P matrix representing the omics data
p	an N by K matrix representing inclusion probability for each latent cluster
mu	an M by K matrix representing cluster-specific means
sigma	an M by M by K array representing cluster-specific covariance
index	an N by M matrix representing missing values in Z
lucid_model	Specifying LUCID model, "early" for early integration, "parallel" for lucid in parallel, "serial" for lucid in serial

Value

a complete dataset of Z
