WARNING: This page is incomplete and outdated!

The purpose of this page is to provide a rough overview of RKWard’s features, as well as a quick reference for the menu items and their use.

This page contains only some very short descriptions. For items in need of more detailed information, please create a new page.

Analysis

Basic statistics

Correlation

Correlation matrix

Calculate a correlation matrix between two or more variables.

Correlation matrix plot

On top the (absolute) value of the correlation is presented plus the result of the cor.test as stars. On bottom, the bivariate scatterplots are plotted with a fitted line. The graph and the code can be found at R Graph Gallery (137) Correlation Matrix, from where was adapted and formatted for RKWard.

Descriptive Statistics

Currently this allows you to calculate the mean, median, range, and standard deviation of one or more variables.

Means

Simple anova

This plug-in allow you to perform a simple anova. Analysis of variance (ANOVA) is a collection of statistical models and their associated procedures which compare means by splitting the overall observed variance into different parts [Wikipedia encyclopedia].

Skewness and Kurtosis

Wilcoxon Tests

Ansari-Bradley Tests

Plots

Box Plot

Density Plot

ECDF Plot

Histogram

Scatterplot

Scatterplot Matrix

Scatterplot matrix plot produces scatterplot matrices with univariate displays down the diagonal. You can choose among Density plot, Boxplot, Histogram, QQplot.
