Plot a Cross-Price Demand Model (Nonlinear)

Usage

# S3 method for class 'cp_model_nls'
plot(
  x,
  data = NULL,
  inv_fun = identity,
  n_points = 100,
  title = NULL,
  xlab = "Price",
  ylab = "Consumption",
  x_trans = "identity",
  y_trans = "identity",
  point_size = 3,
  inverse_fun = deprecated(),
  ...
)

Arguments

x: A cross-price model object from fit_cp_nls with return_all=TRUE.
data: Optional data frame with x and y; if NULL, uses object$data.
inv_fun: Optional function to inverse-transform predictions. Default is identity.
n_points: Number of points used for prediction curve.
title: Optional plot title.
xlab: X-axis label.
ylab: Y-axis label.
x_trans: Transformation for x-axis: "identity", "log10", or "pseudo_log".
y_trans: Transformation for y-axis: "identity", "log10", or "pseudo_log".
point_size: Size of data points.
inverse_fun: Use inv_fun instead.
...: Additional arguments (passed to predict).

Value

A ggplot2 object.
