Oneway Analysis

Examine Relationships between a Continuous Y and a Categorical X Variable

Use the Oneway platform to explore how the distribution of a continuous Y variable differs across groups defined by a categorical X variable. You can evaluate differences in means or variances across groups. Methods includes analysis of variance (ANOVA), analysis of means (ANOM), t tests, equivalence tests, nonparametric tests, exact tests, F tests, and multiple comparisons of means tests. Density and cumulative distribution function (CDF) plots enable you to visualize the distribution of your response by the X categories. For example, you might want to find out how different categories of the same type of drug (X) affect patient pain levels on a numerical scale (Y).

The Oneway platform is the continuous by nominal or ordinal personality of the Fit Y by X platform.
