Test of equality of the concentration parameters for circular data: A test for testing the equality of the concentration parameter among g samples, where g >= 2 for ciruclar data

Description

A test for testing the equality of the concentration parameter among g samples, where g >= 2 for ciruclar data.

Usage

conc.test(u, ina, rads = FALSE)

Arguments

u

A numeric vector containing the values of all samples.

ina

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