Basic statistical tests and utility functions

means - Arithmetic, geometric, and harmonic means.

parammle - Maximum likelihood parameter estimates for DF_Toolbox.

pctile1 - Percentile function (used by summary).

pctile2 - Alternative definition percentile function.

randomttest - Randomization t-test for evaluating residuals from two models.

resize - Resizes arguments to same length.

signtest - Pairwise sign test for evaluating residuals from two models.

summary - Summary statistics for a data vector.

ttest1 - 1 sample t-test.

ttest2e - 2 sample t-test assuming equal variances.

ttest2u - 2 sample t-test assuming unequal variances.

ttest2p - 2 sample paired t-test.

unhist - Create a vector whose values follow an empirical distribution.

wilcoxon - Pairwise Wilcoxon signed rank test for evaluating residuals from two models.

Low-Level Utility Functions

ensurep - ensures that a probability value is between 0 and 1.

ck_function - translates various key strings into standard distribution function strings.
