Scaling Factory

Description

Scaling Factory

Usage

ScalingFactory(method = "NoScaling")

Arguments

method

A scaling method. Available methods are:

• "NoScaling": Identity (Default).

• "ConstantScaling": fit^k with constant exponent. Function ConstantScaling.

• "ThresholdScaling": If the dispersion ratio is larger than 1+threshold, use a constant scaling exponent with a value below 1 (decrease of selection pressure). Function ThresholdScaling.

• If the dispersion ratio is lower than 1-threshold, use a constant scaling exponent with a value above 1 (increase of selection pressure).

• "ContinuousScaling": Use weighted dispersion ratio as scaling exponent. Function ContinuousScaling.

Value

A scaling function.
