ggnbd.cbs.LL

Gamma/Gompertz/NBD parameters - a vector with <code>r</code>,
<code>alpha</code>, <code>b</code>, <code>s</code> and <code>beta</code> in that order.

params

calibration period CBS. It must contain columns for frequency 
<code>x</code>, for recency <code>t.x</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

Calculate the log-likelihood of the Gamma/Gompertz/NBD 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.
