v0.test

Rayleigh Test of Uniformity: Alternative with Specified Mean Direction


Description

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

Usage

v0.test(x, mu0=0, degree=FALSE)

Arguments

x

vector of angular measurements in radians.

mu0

Specified mean direction in alternative hypothesis, measured in the same units (degrees or radians) as the data.

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, r0.bar, and the p-value of the test statistic, p.value.
