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.
bgcnbd.PlotTrackingCum(params, T.cal, T.tot, actual.cu.tracking.data,
xlab = "Week", ylab = "Cumulative Transactions", xticklab = NULL,
title = "Tracking Cumulative Transactions", dropout_at_zero = FALSE)BG/CNBD-k parameters - a vector with k, r, alpha, a and b
in that order.
a vector to represent customers' calibration period lengths (in other words, the "T.cal" column from a customer-by-sufficient-statistic matrix).
end of holdout period. Must be a single value, not a vector.
vector containing the cumulative number of repeat transactions made by customers for each period in the total time period (both calibration and holdout periods).
descriptive label for the x axis.
descriptive label for the y axis.
vector containing a label for each tick mark on the x axis.
title placed on the top-center of the plot.
Boolean; the mbg-methods are simple wrapper methods, which set this parameter to TRUE
Matrix containing actual and expected cumulative repeat transactions.
