%description
Provides advanced statistical methods to describe and predict customers'
purchase behavior in a non-contractual setting. It uses historic
transaction records to fit a probabilistic model, which then allows to
compute quantities of managerial interest on a cohort- as well as on a
customer level (Customer Lifetime Value, Customer Equity, P(alive), etc.).
This package complements the BTYD package by providing several additional
buy-till-you-die models, that have been published in the marketing
literature, but whose implementation are complex and non-trivial. These
models are: NBD [Ehrenberg (1959) <doi:10.2307/2985810>], MBG/NBD
[Batislam et al (2007) <doi:10.1016/j.ijresmar.2006.12.005>], (M)BG/CNBD-k
[Reutterer et al (2020) <doi:10.1016/j.ijresmar.2020.09.002>], Pareto/NBD
(HB) [Abe (2009) <doi:10.1287/mksc.1090.0502>] and Pareto/GGG [Platzer and
Reutterer (2016) <doi:10.1287/mksc.2015.0963>].
