Documentation
data Statistics Source
Abstract type of statistical accumulations. They behave as if the given statistics were computed on the list of values, but they allow a potentially more efficient update of a given value.

Instances

getSumStatistics :: [Double] -> StatisticsSource
Get a statistics that sums up the values.
getStdDevStatistics :: [Double] -> StatisticsSource
Get a statistics for the standard deviation.
getStatisticValue :: Statistics -> DoubleSource
Obtain the value of a statistics.
updateStatistics :: Statistics -> (Double, Double) -> StatisticsSource
In a given statistics replace on value by another. This will only give meaningful results, if the original value was actually part of the statistics.
