### Statistics::Zed - Data-handling and calculations for ratio of observed to standard deviation (zscore) River stage two • 9 direct dependents • 10 total dependents 2 ++

Methods are provided to: + calculate a z-score: ratio of an observed deviation to a standard deviation, with optional continuity correction + convert z-value to normal p-value, and convert p-value to normal-equiv z-value + load, add, save & retrieve ...

### Statistics::ANOVA::JT - Jonckheere-Terpstra statistics and test River stage one • 1 direct dependent • 1 total dependent ++

Calculates Jonckheere-Terpstra statistics for sameness (common population) across given orders of independent variables. The statistics are based on a between-groups pooled ranking of the data, like the Kruskal-Wallis test, but, unlike Kruskall-Walli...

### Statistics::ANOVA::Page - Nonparametric analysis of variance by ranks for trend across repeatedly measured variables (Page and sign tests). River stage one • 1 direct dependent • 1 total dependent ++

Calculates Page statistics for nonparametric analysis of variance across given orders of repeatedly measured variables. Ranks are computed exactly as for the Friedman test, but the ranks are weighted according to the ordinal position of the group/lev...

### Statistics::Sequences::Runs - The Runs Test: Wald-Wolfowitz runs test descriptives, deviation and combinatorics River stage zero No dependents 1 ++

The module returns statistical information re Wald-type runs across a sequence of dichotmous events on one or more consecutive trials. For example, given an accuracy-based sequence composed of matches (H) and misses (M) like (H, H, M, H, M, M, M, M, ...

### Statistics::Standard_Normal - Z scores and percentiles using standard normal table River stage one • 2 direct dependents • 3 total dependents 1 ++

Statistics::Standard_Normal provides convenience functions to convert between Z scores and percentile scores using values taken from a standard normal distribution (that is, a normal distribution with a mean of 0 and a standard deviation of 1). Perce...

### Statistics::Sequences::Turns - Kendall's turning-points test - of peaks and troughs in a numerical sequence River stage zero No dependents ++

Implements Kendall's (1973) "turning point test" of sudden changes as peaks and troughs in the values of a numerical sequence. It is sometimes described as a test of "cyclicity", and often used as a test of randomness. Kendall (1973) introduced this ...
