Description:

This study is about classifying subtypes of pediatric acute lymphoblastic leukemia. The data has been divided into six diagnostic groups (BCR-ABL, E2A-PBX1, Hyperdiploid>50, MLL, T-ALL and TEL-AML1), and one that contains diagnostic samples that did not fit into any one of the above groups (labelled as "Others"). There are 12558 genes. According to the above publication, each group of samples has been randomized into training and testing parts. The number of training and testing samples in each group is listed in the table below.

Group (Class)	Number of Training Samples	Number of Testing Samples
BCR-ABL	9	6
E2A-PBX1	18	9
Hyperdiploid>50	42	22
MLL	14	6
T-ALL	28	15
TEL-AML1	52	27
Others	52	27
Total	215	112
