()[source]¶ Load and return assay of serum free light chain for 7874 subjects.
The dataset has 7874 samples and 9 features:
- age: age in years
- sex: F=female, M=male
- sample.yr: the calendar year in which a blood sample was obtained
- kappa: serum free light chain, kappa portion
- lambda: serum free light chain, lambda portion
- flc.grp: the serum free light chain group for the subject, as used in the original analysis
- creatinine: serum creatinine
- mgus: whether the subject had been diagnosed with monoclonal gammapothy (MGUS)
- chapter: for those who died, a grouping of their primary cause of death by chapter headings of the International Code of Diseases ICD-9
The endpoint is death, which occurred for 2169 subjects (27.5%).
See [1], [2] for further description.
Returns: - x (pandas.DataFrame) – The measurements for each patient.
- y (structured array with 2 fields) – death: boolean indicating whether the subject died
or the event time is right censored.
futime: total length of follow-up or time of death.
