Dear All:
I use -estout- (downloadable from SSC) to obtain a table with several tobit regression models (including a column for the predicted signs). Everything works perfectly, except a minor detail related to the tobit regression.
In the tobit output, there is a line which appears at the bottom of the table and which is named "/sigma". In the -estout- output, I get the same line named "constant". I have then two questions:
- how could I get this line with the "sigma" name and not "constant" which creates a confusion with the constant of the regression
- in an alternative way, how could I simply drop this line in the -estout- output?
I provide below my command lines.
