cbgcnbd.cbs.LL

CBG/CNBD-k parameters - a vector with 'k', <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

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

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