nominalTest: Compute Chi square or Fisher's exact test

Description

Depending on the value of the smallest expected count compute either a \(\chi^2\) or Fisher's exact test.

Usage

nominalTest(tab, limit.exp = 5)

Value

A list containing:

p

The computed \(p\)-value.

test

A string indicating the test that was used.

Arguments

tab

Frequency table, received by applying table() to two nominal variables.

limit.exp

If the smallest expected count is at most limit.exp the \(p\)-value of a Fisher test is returned. Otherwise, a \(\chi^2\) test is computed.

Examples

v1 <- as.factor(round(runif(40, 0, 3)))
v2 <- as.factor(round(runif(40, 2, 3)))
tab <- table(v1, v2)
nominalTest(tab)
