Probability density function of the circular Purkayastha distribution

Description

Probability density function of the circular Purkayastha distribution.

Usage

pcircpurka(u, m, a, rads = FALSE)

Arguments

u	A numerical value, either in radians or in degrees.
m	The mean direction in radians or in degrees.
a	The \alpha parameter of the circular Purkayastha distribution.
rads	If the data are in radians, this should be TRUE and FALSE otherwise.

Details

This value calculates the probability of x being less than theta.

Value

The probability that of x being less than theta, where x follows the circular Purkayastha distribution.
