saturation_hill: Hill Saturation Transformation

In Robyn: Semi-Automated Marketing Mix Modeling (MMM) from Meta Marketing Science

Hill Saturation Transformation

Description

saturation_hill is a two-parametric version of the Hill function that allows the saturation curve to flip between S and C shape.

Produce example plots for the Hill saturation curve.

Usage

saturation_hill(x, alpha, gamma, x_marginal = NULL)

plot_saturation(plot = TRUE)

Arguments

x	Numeric vector.
alpha	Numeric. Alpha controls the shape of the saturation curve. The larger the alpha, the more S-shape. The smaller, the more C-shape.
gamma	Numeric. Gamma controls the inflexion point of the saturation curve. The larger the gamma, the later the inflexion point occurs.
x_marginal	Numeric. When provided, the function returns the Hill-transformed value of the x_marginal input.
plot	Boolean. Do you wish to return the plot?

Value

Numeric values. Transformed values.
