Description Usage Details Value Source Examples
Gene expression (60x7129
) and clinical data (60x4
) are used to predict the response of childhood malignant embryonal tumors of Central Nervous System (CNS) to therapy.

The dataset is composed of 60 patients samples, 21 patients died and 39 survived within 24 months. There are two matrices: genetic data X of size 60x7129
and clinical data D of size 60x4
. There is also a response variable Y
of size 60x1
.
