//
//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.
get GGmd4_28.csv@

//View matrix of conditional independence




//Plot conditional independence between track race.
