Michaelis-Menten Transformation

Description

The Michaelis-Menten mic_men() function is used to fit the spend exposure relationship for paid media variables, when exposure metrics like impressions, clicks or GRPs are provided in paid_media_vars instead of spend metric.

Usage

mic_men(x, Vmax, Km, reverse = FALSE)

Arguments

x	Numeric value or vector. Input media spend when reverse = FALSE. Input media exposure metrics (impression, clicks, GRPs, etc.) when reverse = TRUE.
Vmax	Numeric Indicates maximum rate achieved by the system.
Km	Numeric. The Michaelis constant.
reverse	Boolean. Input media spend when reverse = FALSE. Input media exposure metrics (impression, clicks, GRPs etc.) when reverse = TRUE.

Value

Numeric values. Transformed values.
