Plot the cost per KPI of a fitted model — mrm_plot

This function plots the cost per KPI of a fitted model.

Usage

mrm_plot_costper(
  mrm,
  xrange = NULL,
  length.out = 1000,
  scaled = TRUE,
  cost_per_unit = 1,
  response_rate = 1,
  markup = FALSE
)

Arguments

mrm: A fitted model object. It can be a brmsfit object or a list of brmsfit objects.
xrange: A vector of length 2 specifying the range of x values to plot. If NULL, the range of x values in the data is used.
length.out: An integer specifying the number of points to generate for the x-axis. Default is 1000.
scaled: A logical value indicating whether to plot the scaled response. Default is TRUE.
cost_per_unit: A numeric value specifying the cost per unit of the independent variable. Default is 1.0.
response_rate: A numeric value specifying the response rate to be used in return calculations. Default is 1.0.
markup: A logical value indicating whether to add markup lines to the plot. Default is FALSE.

Value

A ggplot object.

Details

The function plots the cost per KPI of a fitted model object. It uses ggplot2 to create the plot and includes a title with information about the model. If markup is TRUE, it adds vertical lines and segments to indicate the optimal point and the range of returns.
