Anova for circular data {Rfast2}

Analysis of variance for circular data

Description

Analysis of variance for circular data.

Usage

hcf.circaov(u, ina)

lr.circaov(u, ina)

het.circaov(u, ina)

embed.circaov(u, ina)

Arguments

u

A numeric vector containing the data that are expressed in rads.

ina

A numerical or factor variable indicating the group of each value.

Details

The high concentration (hcf.circaov), log-likelihood ratio (lr.circaov), embedding approach (embed.circaov) or the non equal concentration parameters approach (het.circaov) is used.

Value

A vector including:

test

The value of the test statistic.

p-value

The p-value of the test.

kapa

The concentration parameter based on all the data. If the het.circaov is used this argument is not returned.
