PNBD

Introduction In this post, we’ll continue discover the difference between the Cohort Modeling and the Extended PNBD Model with time-invariant covariates. Check here to see the previous post. Data Prepare First let’s import the transactional data, and select the customers who first purchase happened in 2017-2018.

Introducton The original Pareto-NBD Model is awesome, but it does not allow us to add any covariates. In some cases, the covariates may affect the purchase, or the attrition process, or both.

Introduction In the previous posts, we talked about the theoretical part of Pareto/NBD model. This time, we will go over the CLV prediction in R. Customer lifetime value (CLV) is
