示例1: Initialize
void CParam::Initialize(CData &Data){
n_pheno = Data.Y.n_rows ; n_SNP = Data.Y.n_cols ; // constants but stored in CParam for convienence
Data.logY = arma::zeros<arma::mat>(n_pheno,n_SNP) ;
// Note 1. This is used to calculate sum of log y_it when e_it=1.
// 2. (Weak signal) Because e_it=0 with y_it <= 0 by definition (model assumption),
// we will not use log y_it for e_it=0 and store zero here.
// 3. (Strong signal) Also, we put e_it=1 when y_it > threshold // V 1.3.1
for (int i_pheno=0; i_pheno<n_pheno; i_pheno++ ){
for (int i_SNP=0; i_SNP<n_SNP; i_SNP++ ){
