A collection of basic statiscical widgets. These allow for basic statistical tests such as t.test and anova. May also include some higher order statistical functions that are deemed to be of "General Use" such that most users will find them useful or at least interesting.

WidgetDescription
ANOVA
ANOVA-LM
Attributes
Cluster BootClusterwise cluster stability assessment by resampling
Correlation/VarianceCalculate correlation or variance for data. Comparisons can be made across two different matrices or input vectors depending on the connections.
F TestPerforms an F test.
Fast Discrete Fourier Transform
Fisher Exact Test
Generate DistributionsGenerate a variety of distributions for data.
Generic ANOVAPerformed ANOVA on any model or data received. This can result in errors if inappropriate models are supplied.
Heirarchial ClusteringPerforms a variety of clustering functions on a matrix of data. Data can be connected in the RDataFrame form but should contain only numeric data. If not then an error may be reported or the widget may not function as anticipated. Please see the R help for the function hclust or a statistics text on clustering for more information on different clustering methods.
Iterative Signature AlgorithmRun ISA with the default parameters
Kolmogorov-SmirnovKolmogorov-Smirnov test providing a comparison of a fitted distribution with the empirical distribution.
KruskalPerforms the Kruskal Walis test on data.
Linear ModelGenerates a linear model fit to data.
Pairwise T-TestThis widget performs pairwise t-tests on the supplied samples. This is also effective at performing t-tests on two samples if supplied. Data should be supplied in the form of a two columned table with one column representing values and the other the groupings. Use of Melt DF and Column Selector may be helpful in transforming your data.
Partial Least Squares Reg.Beginning module for the pls package to generate a model fit.
Principal ComponentCalculates principal components for a numeric matrix.
Spline FitProduces a spline fit of X/Y data.
t.testPerforms a t-test.
Test For Correlation (Single)Perfors correlation analysis on two vectors. Displays R2, P, and other correlation summary stats.
Wilcoxon TestPerforms the wilcoxon rank sum test on a set of data.
