mbgcnbd.PlotTrackingCum: (M)BG/CNBD-k Tracking Cumulative Transactions Plot

In mplatzer/BTYDplus: Probabilistic Models for Assessing and Predicting your Customer Base

(M)BG/CNBD-k Tracking Cumulative Transactions Plot

Description

Plots the actual and expected cumulative total repeat transactions by all customers for the calibration and holdout periods, and returns this comparison in a matrix.

Usage

mbgcnbd.PlotTrackingCum(
  params,
  T.cal,
  T.tot,
  actual.cu.tracking.data,
  xlab = "Week",
  ylab = "Cumulative Transactions",
  xticklab = NULL,
  title = "Tracking Cumulative Transactions",
  ymax = NULL,
  legend = c("Actual", "Model")
)

bgcnbd.PlotTrackingCum(
  params,
  T.cal,
  T.tot,
  actual.cu.tracking.data,
  xlab = "Week",
  ylab = "Cumulative Transactions",
  xticklab = NULL,
  title = "Tracking Cumulative Transactions",
  ymax = NULL,
  legend = c("Actual", "Model")
)

Arguments

params	A vector with model parameters k, r, alpha, a and b, in that order.
T.cal	A vector to represent customers' calibration period lengths.
T.tot	End of holdout period. Must be a single value, not a vector.
actual.cu.tracking.data	A vector containing the cumulative number of repeat transactions made by customers for each period in the total time period (both calibration and holdout periods).
xlab	Descriptive label for the x axis.
ylab	Descriptive label for the y axis.
xticklab	A vector containing a label for each tick mark on the x axis.
title	Title placed on the top-center of the plot.
ymax	Upper boundary for y axis.
legend	plot legend, defaults to 'Actual' and 'Model'.

Details

Note: Computational time increases with the number of unique values of T.cal.

Value

Matrix containing actual and expected cumulative repeat transactions.
