I have 2 questions.
Does minuit stop if the value of my chi2 is <= edm? Then, the weights I use in the chi2 are critical and leaving them equal to 1 may not be very useful. Should I modify the value of edm (via the tolerance parameter) or is it something I should not touch?
I am using a simulation to test a fitting program. So I generate a simulation out of know parameters. Then I use the same simulation (starting from values different to the true ones) to guess the parameters. What should I use as weights for the chi2 in this case?
