st: RE: Graphical questions(box, histogram, pnorm)
1) This sounds bad. Your Stata installation may be messed up: e.g.
executable and ados not updated synchronously. Sort that out before
addressing 2) and 3).
2) Superimpose a call to -twoway function- using the -addplot()- option.
3) Sounds like a skewed t distribution. Any analogue of -pnorm- is
programmable. In fact it can be done without heavy programming, as it is
just a scatter plot.

I am not able to solve some graphical problems:
1) I would like to do to a box graph.
If I use the following command:
graph7 return, box
everything is fine, however I cannot modify this graph.
When I use the new command:
graph box return
I receive this error message: variable _variables not found
r(111);.What I am doing wrong?
2) I did the histogram of my data and I added a normal distribution:
histogram return, normal
Now, I would like to add to my histogram also a Student's t
distribution. Is there a way to do this?
3) I did the standardized normal probability plot:
pnorm return
Is there a way to do the same for a sweked t distribution. I saw it in
a paper, but I don't know how to replicate it.
