Description

Does Anscombe's inverse sine transformation on a vector input.

Usage

ansc(x, binsize)

Arguments

x

input data vector

binsize

the binomial size corresponding to the observed binomial values.

Value

y

Details

Performs the Anscombe calculation: $A=si{n}^{-1}\sqrt{(x+3/8)/(binsize+3/4)}$.

# NOT RUN {
#generate binomial data:

x<-rbinom(100,10,.5)

y<-ansc(x,10)

#this is now the transformed data.
