bgcnbd.pmf

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

length of time for which we are calculating the expected number of 
transactions.

number of transactions for which probability is calculated.

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

dropout_at_zero

Uses BG/CNBD-k model parameters to return the probability distribution of
purchase frequencies for a random customer in a given time period, i.e.
P(X(t)=x|r,alpha,a,b)

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.
