Applies the modified angular transformation to a vector of counts.

Description

Applies the angular transformation to a vector of counts. A modified transformation is used that is appropriate when N < 50 and the proportion is not between 0.3 and 0.7. The transformation is given by \sin^{-1}{\frac{count + 0.375}{n + 0.75}}.

Usage

angular.mod(count, n)

Arguments

count	The numeric vector of counts.
n	The number(s) of observations from which the count(s) were obtained.

Value

A numeric vector.
