Issue with truncreg function

[Cappuccia Leo]

Hello everyone !
When using "truncreg y x, ll(0)" function, I have the following message "(0 obs truncated)". However, I have a lot of 0 in my variable, the "count if y==0" command gives me "4,915". My variable is coded as "double" with format "%10.0g".
Did anyone encountered this issue and found a solution ?
Thank you for your help !

Kind regards,
L.C

If you have data with zeroes then is not truncated
what you have is censored data
try Tobit for this
