Hi everyone,
I am trying to estimate a tobit model and for some reason i cant figure
out how to get stata to provide the scaling factor score. As you can see
below, i use "fitstat" to get some important fit measures yet the program
doesnt report the scaling factor score. Could someone help with this?
David
