Description
The input power value is rounded to the nearest integer or fractional powers, \pm 1/3, 1/2.
The function is presently designed just for display purposes.
Usage
1
ladder_power(p)
Arguments
p
A numeric power, for use as a transformation of a response, y, of the form y^p,
where p=0 is interpreted to mean log(y)
Details
In use, the transformation via the ladder of powers usually attaches a minus sign to
the transformation when the power < 0, so that the order of the response values
are preserved under the transformation. Thus, a result of power = -0.5 is interpreted
to mean -1 / √{y}.
Value
a named list of two elements: power, the ladder-of-power value, and
name, the name for the transformation
