bkw

BKW multicollinearity diagnostic

CALLING SEQUENCE

[condindex]=bkw(arg1,...,argn)

PARAMETERS

Input

* argi = arguments which can be:

  - a time series

  - a real (nxp) vector

  - a string equal to the name of a time series or a (nxp) real vector between quotes

  - the string 'noprint' if the user doesn't want to print the results of the regression

 

Output

* condindex = the condition number

DESCRIPTION

Computes and prints BKW collinearity variance-decomposition proportions matrix.

EXAMPLE

x = grand(200,5,'nor',0,1);
x(:,1) = ones(200,1);
x(:,3) = x(:,2) + grand(200,1,'nor',0,1)*0.05;
// create multioncolinearity between columns 2 and 3
bkw('x')
// This example is taken from bkw_d. Here the exogenous variables take the form of a matrix x;
// it is entered between quotes, so the exogenous variables will be called x_1, x_2,...
