st: How to calculate the standard errors for the MFX after intreg

[Bo MacInnis <bo@macinnis.org>]

Hi,

My estimation should be -tobit-, and I use -intreg- to obtain robustness 
standard errors. I can calculate the mfx "by hand" but don't know exactly 
how to calculate the standard errors for the marginal effect. I am aware of 
the wonderful tool -dtobit- that does the magic after -tobit-. Does anyone 
know a command to calculate the mfx for -intreg-?

Thank you very much,
Bo MacInnis
