Insensitivity margin in percentage units — margin

A dials parameter for the epsilon tube half-width in psvr MAPE models. Unlike dials::svm_margin() which uses absolute units, this parameter is expressed as a percentage of each target value. The default range [1, 20] means the insensitivity tube spans 1% to 20% of each target.

Usage

margin_percentage(range = c(1, 20), trans = NULL)

Arguments

range: Numeric vector of length 2. Default c(1, 20).
trans: A scales transformation object. Default NULL.

Value

A quant_param dials object.

Examples

margin_percentage()
#> Insensitivity Margin (%) (quantitative)
#> Range: [1, 20]
margin_percentage(range = c(0.5, 10))
#> Insensitivity Margin (%) (quantitative)
#> Range: [0.5, 10]
