HCRT and Cataplexy: Currently this database includes 317 mixed types of variables per patient (e.g., categorical variables and discrete/continuous numeric variables from questionnaire data like features and history of cataplexy, laboratory data of multiple sleep latency test (MSLT) and polysomnography (PSG), biomarkers like CSF hypocretin levels and HLA DQB1*06:02) and 1380 patients from 26 centers with a number of missing data and multicollinearity, making it difficult to analyze with conventional analytics methods.
