Eviews crashes....

[tvonbrasch]

Hi

I am testing if I can use Eviews for a large dataset. When running the code below, Eviews stops working....? (running 8.1, jan 12 2015 build). I believe Eviews has a problem with the command @sumsby(..., trend), could it be due to memory? It would be much better if Eviews could tell me what the problem is instead of crashing.

I just receive an error message due to the negative values in dlog(h).
