Hi,

I want to run the following regression:

threshold inv, threshvar(lagtotaldebtofgdp) regionvars(laggdpgr laginflation lagtradeasofgdp lagpcoftownselectrified lagrealinterestrate)

But I am getting an error message like this:

not enough observations at the specified trim level
r(198);

I have 34 observations. Any help will be much appreciated.

Thanks,

~Subaran.
