Status of ProfileLikelihoodCalculator fit

Hello, running ProfileLikelihoodCalculator, there is a response about the status of the fit both with and without the null hypothesis (see for example here [0]) and you see printed on the stadard output

Status : MINIMIZE=0 

for both of them. My problem is that I didn’t find anywhere a method to check the result of both fit at runtime… I do a lot of these fit and sometimes they fail… how can I check the status of the ProfileLikelihoodCalculator fit?

Thanks for helping



Hi @as5365,
I add in the loop @Jonas, our roofit expert!


Thanks Monica but is there any other roofit expert who can help me? I don’t want to be rude but he never answer… this is the third post (see below for the first 2) where I ask for help and someone else call him in the loop but he never answered… I tried to understand by myself digging in the forum but for these 3 questions I didn’t find any useful indication on what to do and how to solve my problems. I bet he’s very busy and he doesn’t have enough time to answer questions here so I ask again… is there anyone else who could give me some help?



  1. this one looks like a bug… no answer.
  2. no help by anyone

Let me ping @jonas again.
@moneta might also know.
