st: xml_tab and problem with mfx

[ncdcta00@uniroma2.it]

Hi, I have a question about xml_tab. When I constructed the tab for  
regression and  mfx( marginal effects)  in the tab I had  rights  
results for regression but other results different for mfx. Why?

Thanks.
this is the command :

local i=1
while `i'<=4{
 reg `y1' `x1' if country== `i',
 estimates store reg`i'
mfx
estimates store c`i'
  local i=`i'+1
  }
xml_tab reg1 reg2 reg3 reg4 c1 c2 c3 c4
