Calculates the expected cumulative total repeat transactions by all customers for the calibration and holdout periods.
bgcnbd.ExpectedCumulativeTransactions(params, T.cal, T.tot, n.periods.final,
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.
number of time periods in the calibration and holdout periods.
Boolean; the mbg-methods are simple wrapper methods, which set this parameter to TRUE
Vector of expected cumulative total repeat transactions by all customers.
