Dear Statalisters,

I) I have a probit regression, where the dep. var. is a dummy.
I want to graphically see whether my model is affected by heteroskedasticity.Is there a way to plot the probability (instead of the dummy) on the residuals instead?

II) In another step of my analysis I use the vce(cluster varx). I have read there is a test with which one can find out whether clustering is needed: Christopher F. Baum, Austin Nichols, Mark E. Schaffer where working on it at July 2011 (see, http://www.stata.com/meeting/boston10/boston10_baum.pdf). However, I have not found it.
If it is not ready yet, does some of you know some alternative command, or even a way to test it by hand?

Thank you all!
Have a nice w-e
