- Parameters
- posteriordict
- posterior_predictivedict
- predictions: dict
- sample_statsdict
- log_likelihooddict
For stats functions, log likelihood data should be stored here.
- priordict
- prior_predictivedict
- observed_datadict
- constant_datadict
- predictions_constant_data: dict
- warmup_posteriordict
- warmup_posterior_predictivedict
- warmup_predictionsdict
- warmup_log_likelihooddict
- warmup_sample_statsdict
- save_warmupbool
Save warmup iterations InferenceData object. If not defined, use default defined by the rcParams.
- index_originint, optional
- coordsdict[str, iterable]
A dictionary containing the values that are used as index. The key is the name of the dimension, the values are the index values.
- dimsdict[str, List(str)]
A mapping from variables to a list of coordinate names for the variable.
- pred_dimsdict[str, List(str)]
A mapping from variables to a list of coordinate names for predictions.
- pred_coordsdict[str, List(str)]
A mapping from variables to a list of coordinate values for predictions.
- attrsdict
A dictionary containing attributes for different groups.
- kwargsdict
A dictionary containing group attrs. Accepted kwargs are: - posterior_attrs, posterior_warmup_attrs : attrs for posterior group - sample_stats_attrs, sample_stats_warmup_attrs : attrs for sample_stats group - log_likelihood_attrs, log_likelihood_warmup_attrs : attrs for log_likelihood group - posterior_predictive_attrs, posterior_predictive_warmup_attrs : attrs for
posterior_predictive group
predictions_attrs, predictions_warmup_attrs : attrs for predictions group
prior_attrs : attrs for prior group
sample_stats_prior_attrs : attrs for sample_stats_prior group
prior_predictive_attrs : attrs for prior_predictive group
- Returns
- InferenceData object
