Dear Experts,
I have weighted a RooDataSet for my analysis.
But, when I prepared a combined dataset out of these weighted dataset for simultaneous fitting,
my weighted dataset distribution changed and it became unweighted.
The combined dataset is defined as :
RooDataSet combData(“combData”, “combined data”, variables, Index(sample),
Import({{“cat_2016”, wt_mc_16},
{“cat_2017”, wt_mc_17},
{“cat_2018”, wt_mc_18}}));
, where wt_mc_16, wt_mc_17 and wt_mc_18 are my weighted dataset.
Here are the plots attached for both weighted and unweighted dataset.

unweighted dataset:
Best regards,
