structs

class snafu.structs.Data(data)[source]

Bases: object

Container for fluency data used in SNAFU analyses.

This class processes hierarchical and non-hierarchical list data structures into formats that are convenient for analysis, including labeled responses, corrected spellings, intrusions, and IRTs.

Parameters:: data (dict) – Dictionary containing keys: - ‘Xs’ : nested dict of fluency responses - ‘items’ : dict of item labels - ‘structure’ : bool, True if hierarchical - ‘spell_corrected’, ‘perseverations’, ‘intrusions’, ‘categories’, ‘irts’ (optional)

hierarchical()[source]

Process hierarchical (nested) fluency data structure.

Returns:: self – The Data object with hierarchical attributes populated.
Return type:: Data

nonhierarchical()[source]

Process non-hierarchical fluency data, mapping individuals into group space.

Returns:: self – The Data object with flattened attributes populated.
Return type:: Data

subs()[source]

snafu.structs.DataModel(data)[source]

Fill in missing parameters in a data dictionary for generative model configuration.

This sets default values for generative search parameters, such as jump probability, priming effects, and censoring faults.

Parameters:: data (dict) – Dictionary with optional keys like ‘trim’, ‘jump’, ‘jumptype’, ‘priming’, ‘jumponcensored’, ‘censor_fault’, ‘emission_fault’, etc.
Returns:: A dictionary-like object with attribute access to the parameters.
Return type:: dotdict

snafu.structs.Fitinfo(fitinfo)[source]

Fill in missing fields in a dictionary of model-fitting configuration.

Sets default values for priors, graph options, and Conceptual Network parameters.

Parameters:: fitinfo (dict) – Dictionary of model fitting options.
Returns:: Dictionary with all required fitting parameters populated.
Return type:: dotdict

snafu.structs.Irts(irts)[source]

Fill in missing parameters in IRT configuration dictionary.

Supports gamma and ex-Gaussian IRT types. Sets default parameter values if missing.

Parameters:: irts (dict) – Dictionary with keys like ‘irttype’, ‘gamma_beta’, ‘exgauss_lambda’, etc.
Returns:: A dictionary-like object with completed IRT configuration.
Return type:: dotdict
