Finding the series that leads to "log of nonpositive" error

Postby hasan1 » Mon Aug 05, 2019 8:15 pm

Hi All,

I have a model with 60000+ equations. When I try to solve the model (deterministically), I am getting the "log of nonpositive number" error. Obviously a negative value appears somewhere. But the error window doesnt tell us anything else.

My question is, is there a quick way in Eviews to find the series that leads to this error? I dont want to rely on python or something else to find the troublesome series.

Thanks in advance!

Not sure if this is late but if you’re still having the issue, you might want to use a string or scalar as an identifier as you loop through the equations.

For example, say i have 10 equations then:

scalar i=1
for %equation 1 2 3
Estimate your equation here
i=i+1
next

The variable i will tell you where the error is

There may be a more efficient way but this is the first thing that comes to mind
