Rao's Spacing Test of Uniformity

Description

Performs Rao's Spacing Test of uniformity.

Usage

rao.spacing(x, alpha=0, rad=TRUE)

Arguments

x

numeric vector of angular data measured in degrees.

alpha

numeric value specifying the significance level of the test. The default value is 0, in which case, a range for the p-value will be returned. Valid significance levels are 0.10, 0.05, 0.01 and 0.001.

rad

logical value. If true, data will be assumed to be measured radians. If false, data will be assumed to be measured in degrees.

Details

If alpha is specified, critical values are determined from a table of simulated critical points (see reference below). If alpha is not specified, a range for the p-value is determined using the table of simulated critical points.

Value

NULL

Note

The Rao's Spacing Test is performed, and the results are written to the screen.
