Dear all,
My dataset has more than 17000 observations with more than 100 variables. For my analysis I have to generate quite many variables based on the initial variables for a Tanslog function with many interacted terms (56 items). But when I run my model, I got the error message: r(1400). I checked the stata help, it says:
numerical overflow;
You have attempted something that, in the midst of the necessary
calculations, has resulted in something too large for Stata to
deal with accurately. Most commonly, this is an attempt to
estimate a model (say with regress) with more than 2,147,483,647
effective observations. This effective number could be reached
with far fewer observations if you were running a frequency-weighted
model.

But it seems that there is no suggestion for solutions to this problem. How can I solve it?
Thank you!
Linda
