plt_dfb

plots dfbetas

CALLING SEQUENCE

plt_dfb(res)

PARAMETERS

Input

* res = the results typed list of function dfbeta

 

Output

* nothing (printed on a graphic window)

DESCRIPTION

Plots the dfbetas coefficients of an ols regression. Dfbetas are plotted 4 by for 4 on the same graphic window.

EXAMPLE

exo = grand(100,6,'nor',0,1);
exo(:,1) = ones(100,1);
exo(:,3) = exo(:,2) + grand(100,1,'nor',0,1)*0.05;
 
bet = ones(6,1);
 
endo = exo*bet + grand(100,1,'nor',0,1);
 
// now add a few outliers
endo(50,1) = 10.0;
endo(70,1) = -10.0;
 
// run dfbeta without printing and plotting the results
res = dfbeta('endo','exo','noprint');
 
// now plot the result
plt_dfb(res)
