RE: st: Tobit graphics

["Kakouros, Nikolaos" <Nikolaos.Kakouros@umassmemorial.org>]

Ro'I,
Many thanks - that works great!  I changed recastci(rline) to (rarea) to get the same shaded CI effect as lfitci.

Now - is it possible to show this data on the same graph as the other dataset's scatter and lfitci?
I tried 
marginsplot, recast(line) recastci(rarea) addplot(twoway (scatter x y) (lfictci x2 y2) (scatter x2 y2))

I also tried
Twoway (marginsplot, recast(line) recastci(rarea) addplot(scatter x y)) (lfictci x2 y2) (scatter x2 y2)


with no luck...
Any suggestions?

Many thanks,

Nikos

Hi Nikos,

I think the following should work for you:
tobit x y, ll(0)
margins, at(y=(0(10)100))
marginsplot, recast(line) recastci(rline) addplot(scatter x y)

With the margins parameters adjusted for your data.

Cheers,
Ro'i
