Rayleigh Test of Uniformity: General Unimodal Alternative

Description

Performs a Rayleigh test of uniformity, assessing the significance of the mean resultant length. The alternative hypothesis is a unimodal distribution with unknown mean direction and unknown mean resultant length.

Usage

r.test(x, degree=FALSE)

Arguments

x vector of angular measurements in radians.
degree logical flag: if TRUE, data is assumed to be measured in degrees rather than radians. Default is FALSE.

Value

Returns a list with two components: the mean resultant length, r.bar, and the p-value of the test statistic, p.value.
