Returns the number of repeat transactions that a randomly chosen customer (for whom we have no prior information) is expected to make in a given time period.
bgcnbd.Expectation(params, t, dropout_at_zero = FALSE)BG/CNBD-k parameters - a vector with k, r, alpha, a and b
in that order.
length of time for which we are calculating the expected number of repeat transactions.
Boolean; the mbg-methods are simple wrapper methods, which set this parameter to TRUE
