Fitting Tutorial with BOOTSTRAPPING

This notebook tutorial runs in only one mass bin at the time

Define Waves for Fit (and input initial values of minuit and fitted parameters).*

In this example (as expected by the defined amplitude)\ each wave is defined by (epsilon.l.m) and each parameter has a real and imaginary part.\ i.e a epsilon=-1, l=1 (P wave), m=1 will produce Vs(r.-1.1.1) and Vs(i.-1.1.1) names.\ (In this example the imaginary part of the P-wave is kept fixed at 0 value\ in the fit)

Read data and montecarlos (accepted and generated) samples

Binning of the data/monte-carlo and define amplitude (function) to fit*

Here the user difine number of bins, variable to be binned and range

Check that bins have enough number of events for fit


Fitting with Minuit and Extended LogLikelihood
