mbgcnbd.PlotTrackingInc: (M)BG/CNBD-k Tracking Incremental Transactions Comparison

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

Description

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

Usage

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

bgcnbd.PlotTrackingInc(
  params,
  T.cal,
  T.tot,
  actual.inc.tracking.data,
  xlab = "Week",
  ylab = "Transactions",
  xticklab = NULL,
  title = "Tracking Weekly 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.inc.tracking.data	A vector containing the incremental 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 incremental repeat transactions.
