- fixed many of the numpy warnings as the result of fitting
- added optional
initial_params
to all models - Added
conditional_probability_of_n_purchases_up_to_time
toParetoNBDFitter
- Fixed a bug in
expected_cumulative_transactions
andplot_cumulative_transactions
- adding new
save_model
andload_model
functions to all fitters. This will save the model locally as a pickle file. observation_period_end
insummary_data_from_transaction_data
andcalibration_and_holdout_data
now defaults to the max date in the dataset, instead of current time.- improved stability of estimators.
- improve Runtime warnings.
- All fitters are now in a local file. This doesn't change the API however.
