问题
I've been using BTYD package for predicting customer churn and number of orders in the future, but I find the included models (Pareto/NBD, BG/NBD and BG/BB) limited in the sense that they only take recency, frequency, age and monetary value into account. Using these values I receive accuracy of up to 80% but I'm sure this could be improved by incorporating more meaningful predictors into the model. Is it possible in this package? I couldn't find any information about it in the vignette. Any help is welcome, thanks!
