my questions concerns the fit option “L”. I have a histogram containing counts. I substract another histogram, which has an non-integer bincontent. I want to fit the resulting difference histogram with vonsequently non-integer bin content with an expontial function. I tried the log Likelihood option “L” and “WL” (same result with different errors). For comparison I also did a chi2 fit and I get a different result. The difference has a significant impact on the outcome of my analysis.
To my understanding the log Likelihood is prefered for a histogram containing counts, but in my case I first substract another histogram and grt the non-integer bin content. Can you please help me, whether the Log Likelihood fit option or the chi2 fit would be the correct way to deal with the situation?
