bgcnbd.cbs.LL

BG/CNBD-k parameters - a vector with <code>k</code>, <code>r</code>,
<code>alpha</code>, <code>a</code> and <code>b</code> in that order.

params

calibration period CBS. It must contain columns for frequency 
<code>x</code>, for recency <code>t.x</code>, for sum of logarithmic interpurchase
times <code>litt</code> and total time observed <code>T.cal</code>. Optionally a column
<code>custs</code> can be provided, which represents number of customers with a
specific combination of frequency <code>x</code> and <code>T.cal</code>.

cal.cbs

Boolean; the mbg-methods are simple wrapper methods,
which set this parameter to TRUE

dropout_at_zero

Calculate the log-likelihood of the BG/CNBD-k model

Extends the functionality of BTYD package by providing methods for
parameter estimation and scoring for NBD, G/G/NBD, MBG/NBD, BG/CNBD-k and
MBG/CNBD-k models, as well as MCMC samples for Pareto/NBD,
Abe's Pareto/NBD variant and Pareto/GGG.
