The following statistics can be rapidly analysed:
Chi-squared, Fisher’s and other exact tests of independence or goodness-of-fit; Cochran–Mantel– Haenszel test; Descriptive statistics: central tendency, dispersion, standard error, confidence limits, normality, homoscedasticity, data transformations, multiple comparisons; one-way to three-way or nested anova; Kruskal–Wallis test; Wilcoxon signed-rank test; t–tests; simple and step-wise multiple linear regression; Pearson and Kendall correlations; analysis of covariance; simple, step-wise multiple, ordinal and conditional logistic regression; principal component analyses or factor analyses of mixed data; aligned rank transform for repeated measures. Survival studies.
Recent studies concluded include the following. ONLY THE MOST IMPORTANT STATISTICS USED ARE SHOWN HERE. USUALLY THERE WERE HUNDREDS OF PARAMETERS TO BE ASSESSED (!)
