The object is composed of a list of two matrices: genetic data X of size 78x4348
and clinical data D of size 78x7
. There is also a response variable Y of size 78x1
. The clinical data contain information on 78 primary breast cancers (34 from patients who developed metastases within 5 years and 44 from patients who continue to be disease-free after a period of at least 5 years) which have
been selected from patients who were lymph node negative and under 55 years of age at diagnosis.
