The
n+1 distribution parameters
bi,
also known as this distribution's
interval boundaries, shall satisfy the relation
bi<bi+1 for
i=0,…,n−1. Unless specified otherwise,
the remaining
n+1 distribution parameters are calculated as
ρk=wk/S for
k=0,…,n, in which the values
wk,
commonly known as the
weights at boundaries, shall be non-negative, non-NaN, and non-infinity
. Moreover, the following relation shall hold:
