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).
- Parameters
- breaks(N,)
array
ofpython:float
The boundaries of successive intervals.
- totals(N-1,)
array
ofpython:float
The weight for each interval.
- breaks(N,)
- Returns
- f
python:callable()
A cumulative distribution function corresponding to the piecewise-constant probability distribution given by breaks, weights
- f
