tidy.manova: Tidy a(n) manova object

In broom: Convert Statistical Objects into Tidy Tibbles

Tidy a(n) manova object

Description

Tidy summarizes information about the components of a model. A model component might be a single term in a regression, a single hypothesis, a cluster, or a class. Exactly what tidy considers to be a model component varies across models but is usually self-evident. If a model has several distinct types of components, you will need to specify which components to return.

Usage

## S3 method for class 'manova'
tidy(x, test = "Pillai", ...)

Arguments

x	A manova object return from stats::manova().
test	One of "Pillai" (Pillai's trace), "Wilks" (Wilk's lambda), "Hotelling-Lawley" (Hotelling-Lawley trace) or "Roy" (Roy's greatest root) indicating which test statistic should be used. Defaults to "Pillai".
...	Arguments passed on to stats::summary.manova object An object of class "manova" or an aov object with multiple responses. intercept logical. If TRUE, the intercept term is included in the table. tol tolerance to be used in deciding if the residuals are rank-deficient: see qr.

Details

Depending on which test statistic is specified only one of pillai, wilks, hl or roy is included.

Value

A tibble::tibble() with columns:

den.df	Degrees of freedom of the denominator.
num.df	Degrees of freedom.
p.value	The two-sided p-value associated with the observed statistic.
statistic	The value of a T-statistic to use in a hypothesis that the regression term is non-zero.
term	The name of the regression term.
pillai	Pillai's trace.
wilks	Wilk's lambda.
hl	Hotelling-Lawley trace.
roy	Roy's greatest root.
