astropy.stats.cdf_from_intervals(breaks, totals)[source]

Construct a callable piecewise-linear CDF from a pair of arrays.

Take a pair of arrays in the format returned by fold_intervals and make a callable cumulative distribution function on the interval (0,1).

breaks : array of floats of length N

The boundaries of successive intervals.

totals : array of floats of length N-1

The weight for each interval.

f : callable

A cumulative distribution function corresponding to the piecewise-constant probability distribution given by breaks, weights
