re: st: Reversed coefficient sign for exponential MLE vs. ereg

[Christopher Baum <kit.baum@bc.edu>]

I am trying to implement the ereg (exponential regression) estimator using ML, and am encountering something odd. I have written a .do file as follows...

program define myexponential
	version 10.0
	args lnf x
	local lambda = exp(`x')
	quietly replace `lnf' = ln(`lambda') - `lambda'*$ML_y1
end


As ereg has been obsolete since Stata version 8, why not frame this question in terms of currently supported and documented commands? Unless someone
has a Stata 7.0 manual, how would they know what the syntax for ereg is?
