circular (version 0.4-93)

rayleigh.test: Rayleigh Test of Uniformity

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 if mu is NULL otherwise the alternative hypothesis is a unimodal distribution with a specified mean direction and unknown mean resultant length.

Usage

rayleigh.test(x, mu = NULL)
# S3 method for rayleigh.test
print(x, digits=4, …)

Arguments

x

a vector. The object is coerced to class circular.

mu

Specified mean direction in alternative hypothesis as a circular object.

digits

integer indicating the precision to be used.

…

further arguments passed to or from other methods.

Value

Returns a list with three components: the mean resultant length, statistic, the p-value of the test statistic, p.value and the value of the alternative mean direction mu.
