Hi everyone,

I'm having a bit of trouble with a model with a threshold effect. I want it to return a 0 until a threshold is passed, and then return a 1. Currently I have that as
IF THEN ELSE (Threshold difference<0,0,1)

However, what happens is that once the threshold difference goes back to zero or below, the 0 is reinputted into the variable instead of the 1. Is there a way to structure a statement so that once the threshold is crossed it permanently becomes a 1?

Many thanks,
Brian

Will SAMPLE IF TRUE do the job?

Hi

Here is joined a model that does the same thing that the sample if true without using it and is eventually easier to understand.

Many thanks to both of you for your prompt and helpful replies, I think both of these should do the trick!

Best,
Brian
