Power Transformation

Creates a power transformation: x^lambda (Box-Cox family).

PowerTransform(lambda)

Arguments

lambda

Power parameter (lambda = 0 is log, lambda = 0.5 is sqrt)

Value

A PowerTransform object

Examples

if (FALSE) { # \dontrun{
# Square root (equivalent to SquareRootTransform)
trans <- PowerTransform(lambda = 0.5)

# Cube root
trans <- PowerTransform(lambda = 1 / 3)
} # }
