Hello root family,
I had a problem with some weights in the TMVA Fatal error TMVA signalweight, for that reason I was checking for the beginning and I notice that in the Roofit in the pdf of exponencial (for my background signal) I have the next warning
but they continue and compile right, and show me the values for my parameters. After that I’m able to calculate and save the Weights.
My question is if this Warning “p.d.f value is Not-a-Number (-nan), forcing value to zero @ pdf=exponencial=inf/-nan, n=Nb=1.13659e+06” is causing me the error in my TMVA Fatal error TMVA signalweight
And I want to know how to fix this warning, beacuse in the other parameters Root does not show me that warning
This is my code:
