Description

v1.4.8.0 New features:
  1. add methods vars_power,vars_exp and vars_formula that allows to create functional variables (and properly store intermediate objects) 
    pdf = ...
v1  = pdf.vars_power   ( a  ,  2 ) ## a^2
v2  = pdf.vars_power   ( 10 ,  b ) ## 10^b
v3  = pdf.vars_power   ( a  ,  b ) ## a^b 
v4  = pdf.vars.exp     ( a  , -1 ) ## exp(-a)
v5  = pdf.vars.exp     ( a  ,  b ) ## exp(a*b)
v6  = pdf.vars_formula ( '{}*{}/{}'       , vars = ( a , b , c ) ) 
v7  = pdf.vars_formula ( 'x[0]*x[1]/x[2]' , vars = ( a , b , c ) )
  2. add Asymptotic (also AsymptoticErr, AsymptoticError, AsymptoticErrors, case-insensitive) keyword for fit-related methods, that (for ROOT versions starting from 6.19) is decoded to ROOT.RooFit.AsymptoticError(...)
  3. add possible file-extensions for canvas-plots :
    canvas >> 'plots.tgz' ## make plot in all formats and store them in tar/GZIP  format
canvas >> 'plots.tbz' ## make plot in all formats and store them in tar/BZIP2 format
canvas >> 'plots.txz' ## make plot in all formats and store them in tar/LZMA  format
  4. Improve a bit the interface for BLUE: Best Linear Unbiased Estimator : combination of correlated measurements
  5. add test for BLUE ostap/stats/tests/test_stats_blue.py
  6. add SciPy/FFT-based convolution for functions `ostap/math/sp_convolution.py'
  7. add SciPy-based bspline interpolation for functions `ostap/math/sp_interpolation.py'
  8. imporve pseudo-abstract operations `ostap/math/operations.py'
  9. extend interpolation tests
  10. add simple shapes to probe signal/background interference Ostap::Models::BWI and BWI_pdf
  11. Fixes for ROOT 6.20/00
Backward incompatible changes
  1. Remove all Rotated-stuff
Bug fixes:
  1. fix typo in treatment of pdf.draw ( ,,, , in_range(1/2/3) = ... , )
  2. fix some new typos/errors in ostap.math
