| gov.sandia.cognition.statistics.method | Provides algorithms for evaluating statistical data and conducting statistical inference, particularly frequentist methods. | 
| Modifier and Type | Class and Description | 
|---|---|
| class  | AnalysisOfVarianceOneWayAnalysis of Variance single-factor null-hypothesis testing procedure,
 usually called "1-way ANOVA". | 
| class  | BonferroniCorrectionThe Bonferroni correction takes a pair-wise null-hypothesis test and
 generalizes it to multiple comparisons by adjusting the requisite p-value
 to find significance as alpha / NumComparisons. | 
| class  | ChiSquareConfidenceThis is the chi-square goodness-of-fit test. | 
| class  | FisherSignConfidenceThis is an implementation of the Fisher Sign Test, which is a robust
 nonparameteric test to determine if two groups have a different mean. | 
| class  | FriedmanConfidenceThe Friedman test determines if the rankings associated with various
 treatments are equal. | 
| class  | GaussianConfidenceThis test is sometimes called the "Z test"
 Defines a range of values that the statistic can take, as well as the
 confidence that the statistic is between the lower and upper bounds. | 
| class  | KolmogorovSmirnovConfidencePerforms a Kolmogorov-Smirnov Confidence Test. | 
| class  | MannWhitneyUConfidencePerforms a Mann-Whitney U-test on the given data (usually simply called a
 "U-test", sometimes called a Wilcoxon-Mann-Whitney U-test, or
 Wilcoxon rank-sum test). | 
| class  | NemenyiConfidenceThe Nemenyi test is the rank-based analogue of the Tukey multiple-comparison
 test. | 
| class  | SidakCorrectionThe Sidak correction takes a pair-wise null-hypothesis test and
 generalizes it to multiple comparisons by adjusting the requisite p-value
 to find significance as alpha / NumComparisons. | 
| class  | StudentTConfidenceThis class implements Student's t-tests for different uses. | 
| class  | TukeyKramerConfidenceTukey-Kramer test is the multiple-comparison generalization of the unpaired
 Student's t-test when conducting multiple comparisons. | 
| class  | WilcoxonSignedRankConfidenceThis is a Wilcoxon Signed-Rank Sum test, which performs a pair-wise test
 to determine if two datasets are different. |
