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

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

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.

Value

Matrix containing actual and expected incremental repeat transactions.
