Changelog

0.9.0

  • 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 to ParetoNBDFitter
  • Fixed a bug in expected_cumulative_transactions and plot_cumulative_transactions

0.8.1

  • adding new save_model and load_model functions to all fitters. This will save the model locally as a pickle file.
  • observation_period_end in summary_data_from_transaction_data and calibration_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.
