Functions
VectorDouble	Db::statisticsMulti (const VectorString &names, bool flagIso=true, bool verbose=false, const String &title="")

Detailed Description

These functions calculate the correlation matrix based on a set of variables contained in a Db. Although the result stands as a matrix, they are returned as a Vector.

Parameters

names	Vector of target variable names
flagIso	The statistics are calculated only for samples where all target variables have defined values
verbose	Verbose flag
title	If verbose, the title of the printed statistics.

Returns

These functions return a vector containing the correlation matrix.
