angular.mod {asremlPlus} | R Documentation |
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}} arcsin( sqrt( (count + 0.375) / (n + 0.75) ) ).
angular.mod(count, n)
count |
The numeric vector of counts. |
n |
The number(s) of observations from which the count(s) were obtained. |
A numeric vector.
