Welcome to the pyhf wiki!
The main call is:
hfpdf.pdf(pars, data)
which transforms a pair of data (the observed counts in the channels + the implied observations of the auxiliary measurements) and parameters (parameters of interest nuisance parameters) into a single float
data (real and implied) - [ channel 1 | channel 2 | ... | channel n | aux meas 1 | aux meas 2 | ... | aux meas m] ---------- +-> | channel 1 | is concatenation of [ c1_bin1 | c1_bin2 | ... | c1_binN] parameters (concatenation of all parameters of interest + nuisance parameters) - [ par 1 | .... | par n ] | | Computational Graph | v [ ] single float pdf value
