Module value

Bin Value types for ND-histograms

This module contains implementations of types intended to be used as bin value types in Histograms. See crate front page for a summary of the provided types.

Structs

Mean

This ndhistogram bin value computes the mean of the data samples provided when filling.

Sum

ndhistogram bin value type for filling unweighted values. Analogous to WeightedSum. Methods returning variance and standard deviation assume Poisson statistics.

WeightedMean

ndhistogram bin value computes the mean of the data samples provided when filling.

WeightedSum

ndhistogram bin value type that calculates a weight sum. It also provides methods to keep track of the sum of weights squared. This is used to provide estimates of the statistical error on the weighted sum. This performs a similar function to Sumw2 that ROOT users may be familiar with.
