Nishant:
If you are using Stata 9, than -stphtest- is out of date and you can
better use -estat phtest-, but that does not answer your question.
You can pile up almost any options you can use after -twoway- after
-estat phtest, plot(varname)- (or -stphtest, plot(varname)-). In your
case you want to change the title on the y-axis, so you can add
ytitle("whatever"). This is illustrated in the example below.
As I understand it, the plot option just shows a scatter plot of scaled
Schoenfeld residuals against time with a lowess smooth fitted through
it. If I do that by hand my lowess smooth is a lot smoother than the
result from -estat phtest-, but the footnote indicates that the same
bandwidth is used. Does anybody have any ideas?
HTH,
Maarten
