Full list of smallStats routines

(Still under construction, as new routines are added)

Parametric, one column

  • general and more exotic averages
    sum, mean,sum of squares, standard dev. population and sample, standard error of the mean, coefficient of variation, confidence interval 5%
    geometric, harmonic, quadratic and
    olympic mean, mean of absolute values
  • skewness - kurtosis, as moments and
    as k-statistics (g1, g2)
  • standard errors (of median, sd, G1, G2)
  • serial independence (eta, 1.0-eta/2)
  • test for normality (with qq plot, Shapiro-Wilk, D'Agostino-Pearson))

Parametric, two columns

  • difference between means
    Student's t-Test, confidence limits for difference, Welch df star)
  • paired comparisons (ANOVA with remainder)
  • equality of variances (F-test)
  • distances
    (angular, Euclidean, Cittyblock (Manhattan, boxcar, absolute value), Canberra, Bray-Curtis (Sorensen), Kulczynski an Hellinger

Parametric, more columns

Non-parametric

  • sign test
  • Kruskal - Wallis
  • Mann - Whitney U
