R Documentation

Analysis of Variance F statistic

Description

Calculates the analysis of variance F statistic.

Usage

anovaF(y, w, calcOptions = NULL)

Arguments

`y`	a vector or matrix of outcomes.
`w`	a vector or matrix of assignments.
`calcOptions`	a list of options for calculating the analysis of variance (ANOVA) F statistic (if necessary). `calcOptions$block` can denote a block variable to be accounted for. `calcOptions$row` and `calcOptions$col` can denote rows and columns to be accounted for in a Latin square design.

Details

Returns the F statistic calculated in an analysis of variance of a linear model with no interaction terms.

Value

An analysis of variance F statistic.

Examples

## 1 treatment factor with 3 levels
## Assignments and outcomes
w = c(1,1,1,1,2,2,2,2,3,3,3,3)
y = c(4,6,5,7,4,7,11,9,8,12,9,9)
anovaF(y, w)

## 1 treatment factor with 3 levels, with block
## Assignments, blocks, and outcomes
w = c(1,1,1,1,2,2,2,2,3,3,3,3)
x = c(1,1,2,2,1,1,2,2,1,1,2,2)
y = c(4,6,5,7,4,7,11,9,8,12,9,9)
anovaF(y, w, calcOptions = list(block = x))
