Hi
I am actually running the White test for correcting Heteroscedasticity.  I
used sandwich() & car(), however the output shows the updated t test of
coefficients, with revised Standard Errors, however the estimates remained
same.  My problem is that the residuals formed a pattern in the original
regression equation.  After running the White's test, I got some new
standard errors - but from here I didn't understand how to plot the
residuals (or) how to correct the estimates??  Can some one direct me in
this regard..

Best,

Kishore/..
