Folded Power Transformation
Description
The name “folded Power Transformation” is used because this does for power transformations what Tukey's folded logarithm does for the logarithmic tranformation. The function calculates
where is the power and
is a positive
offset that ensures that
is
greater than 0 and finite.
Usage
fpower(p, lambda, eps)
Arguments
p |
Mortality proportion |
lambda |
Power |
eps |
If |
Value
The transformed values of fpower(p)
.
Examples
p <- (0:10)/10
ytrans <- fpower(p, lambda=0.25, eps=1/450)
