params |
A vector with model parameters |
T.star |
Length of the holdout period. |
cal.cbs |
Calibration period CBS (customer by sufficient statistic). It must contain columns for frequency ('x'), recency ('t.x') and total time observed ('T.cal'). |
x.star |
Vector of transactions made by each customer in the holdout period. |
censor |
Cutoff point for number of transactions in plot. |
xlab |
Descriptive label for the x axis. |
ylab |
Descriptive label for the x 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. |
Holdout period transaction frequency comparison matrix (actual vs. expected).
