supernova (version 2.1.1)

supernova: supernova

Description

An alternative set of summary statistics for ANOVA. Sums of squares, degrees of freedom, mean squares, and F value are all computed with Type III sums of squares. This package adds proportional reduction in error, an explicit summary of the whole model, and separate formatting of p values and is intended to match the output used in Judd, McClelland, and Ryan (2017).

Usage

supernova(fit, type = 3)
superanova(fit, type = 3)

Arguments

fit

A fitted lm object

type

The type of sums of squares to calculate:

• 1, I, and sequential compute Type I SS.

• 2, II, and hierarchical compute Type II SS.

• 3, III, and orthogonal compute Type III SS.

Value

An object of the class supernova, which has a clean print method for displaying the ANOVA table in the console as well as a named list:

tbl

The ANOVA table as a data.frame

fit

The original lm object being tested

models

Models created by generate_models

Details

superanova() is an alias of supernova()
