plot.clv.fitted.spending: Plot expected and actual mean spending per transaction

Description

Compares the density of the observed average spending per transaction (empirical distribution) to the model's distribution of mean transaction spending (weighted by the actual number of transactions).

Usage

# S3 method for clv.fitted.spending
plot(x, n = 256, verbose = TRUE, ...)
# S4 method for clv.fitted.spending
plot(x, n = 256, verbose = TRUE, ...)

Arguments

x

The fitted spending model to plot

n

Number of points at which the empirical and model density are calculated. Should be a power of two.

verbose

Show details about the running of the function.

...

Ignored

Value

An object of class ggplot from package ggplot2 is returned by default.
