Calculate the log-likelihood of the NBD model

Usage

nbd.cbs.LL(params, cal.cbs)

Arguments

params	NBD parameters - a vector with r and alpha, in that order.
cal.cbs	Calibration period CBS. It must contain columns for frequency x and total time observed T.cal.

Value

The total log-likelihood for the provided data.

Examples

data("groceryElog")
cbs <- elog2cbs(groceryElog)
params <- nbd.EstimateParameters(cbs)
