Simulate data according to BG/CNBD-k model assumptions
bgcnbd.GenerateData(n, T.cal, T.star = NULL, params, return.elog = FALSE,
dropout_at_zero = FALSE)number of customers
length of calibration period; if vector then it is assumed that customers have different "birth" dates, i.e. max(T.cal)-T.cal
length(s) of holdout period(s); assumed to be same for all customers
BG/CNBD-k parameters - a vector with k, r,
alpha, a and b in that order.
boolean - if TRUE then the event log is returned in
addition to the CBS summary
Boolean; the mbg-methods are simple wrapper methods, which set this parameter to TRUE
list with elements cbs and elog containing data.frames
