levpet tfp estimation - issue with predict

[Manish Sharma]

Hello
I am using Levinsohn Petrin for productivity estimation using revenue method. After getting result for levpet command, I'm not able to get results for "predict TFP, omega".
The sequence is as follows:

xtset id Year, yearly
levpet lnOutput xxxxx - Results
predict TFP, omega - No result

I will deeply appreciate help or suggestion to resolve this..

Regards
Manish

II got the result in data section. The separate TFP column appears similar to logarithmic generating function. Now, I have to interpret the result. Thanks.
