Descriptive statistics for Ecko: mean, median, mode, variance, stdev, quantiles. Pure - no capabilities.

import stats

Pure computation: it declares no capabilities, so it cannot touch the network, the filesystem or the environment.

Version 0.9.5 - source - MIT.

mean(xs)

The arithmetic mean. Raises on an empty list.

median(xs)

The middle value, averaging the two middle values for an even count. Raises on an empty list.

mode(xs)

The most frequent value; on a tie, the smallest (deterministic).

variance(xs)

Sample variance / standard deviation (n - 1).

stdev(xs)

Sample standard deviation (n-1) - the square root of variance.

pvariance(xs)

Population variance / standard deviation (n).

pstdev(xs)

Population standard deviation (n) - the square root of pvariance.

quantile(xs, q)

The q-th quantile (q in 0..1) by linear interpolation between order statistics.

range_of(xs)

max - min.
