//Gaussian Graphical Model (GGM) analysis command
//
//This command is used to conditional independent each other of items.
//This command calculate partial correlation from correlation matrix
//and gets conditional independent between items by Wermuth & Scheidt method.
//(Quation)
//This command use correration matorix as input;
//Syntax
//ggm variables list.
//Option
//method:data type corr/row (corr)
//num:num of records (101)
//
//Example 1
//Get conditional independent between point of track race.

//View matrix of conditional independence
//Plot conditional independence between track race.
