leukemia: Expression levels recorded in leukemia patients.

Description Usage Format Source References Examples

Description

Expression levels recorded for 3,571 genes in 72 patients with leukemia (Golub et al, 1999). The binary outcome encodes the disease subtype: acute lymphobastic leukemia (ALL) or acute myeloid leukemia (AML).

Format

Data are represented as a 72 x 3,571 matrix x of gene expression values, and a vector y of 72 binary disease outcomes.
