Some models (https://github.com/csmfindling/behavior_models/blob/master/models/expSmoothing_prevAction.py#L29, https://github.com/csmfindling/behavior_models/blob/master/models/expSmoothing_stimside.py#L34) claim to return the `loglikelihood` variable, but do not. For clarify, could you make the documentation consistent with the code?
