Inference data with groups:
	> posterior
	> posterior_predictive
	> sample_stats
	> prior
	> prior_predictive
	> observed_data
	> log_likelihood
	> constant_data
	> predictions
	> predictions_constant_data

In this example, each variable has as dimension a combination of the following 3: chain, draw and developer. Moreover, each dimension has specific coordinate values. In the case of chain and draw it is an integer identifier starting at 0; in the case of developer dimension, its coordinate values are the following strings: ["Alice", "Bob", "Cole", "Danielle", "Erika"].
