eegprep.std_addvarlevel

eegprep.std_addvarlevel(STUDY, designind=None)

Return STUDY with one/two design-variable levels.

EEGLAB marks variables from per-trial metadata as first-level ("one") and stable dataset/subject metadata as second-level ("two"). Dataset metadata that changes within one subject is first-level because it cannot be modeled as an inter-subject factor.

Parameters:

• STUDY (dict[str, Any])

• designind (int | list[int] | None)

Return type:

dict[str, Any]
