v1.9.9.8

New features:

Backward incompatible:

Bug fixes:

1. fix a bug in dataset.duplicates : not all duplicated entries were listed.

v1.9.9.6

v1.9.9.6

New features:

1. add Ostap::MoreRooFit::ProfileLL to allow bypass subtraction of the minimum for profile graphs. From now the profile graph , obtaibed from PDF.grpah_profile with option subtract=False is not min-subtracted. It is useful e.g, for evalauation of discrete systematic uncertainties using profile-likelihood method
2. make attempts to avoid decolorisation of previously createe frames/RooPlot objects

Backward incompatible:

1. reparameterise Bukin2_pdf in terms of varsigma and asymmetry instead of varsig

Bug fixes:
