Subject   st: plotting a regression function with time-dummies indicating structural breaks
Date   Tue, 03 May 2011 11:10:43 +0200

Hi everybody,
I wonder if there is an easy way to plot a regression of the form:

y_t = b_0 + b_1*TIME_t + Dummy_1*(b_2 + b_3*TIME_t) + b_4*Dummy_2

So far I tried:
gen x = TIME_t
twoway ///
	(tsline y) ///
	(function y = b_0 + b_1*x + Dummy_1*(b_2 + b_3*x) + b_4*Dummy_2, ///
		range(`first_year' `last_year'))

I seem to have a problem with the range, because the resulting graph just
covers one third of the graph. But the shape seems to look ok, just
compressed.

Hopefully there is a nice way of plotting such stuff without the -function-
command or some one has a hint regarding the range problem.

Kind regards
Oliver
