The medulloblastoma dataset
Description
The dataset, which is available on https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE468, contains 23 patients with medulloblastoma, and each patient has 2059 gene expression values. The response contains 2 classes: metastatic (M+) or non-metastatic (M0). After removing the missing and duplicate values, the dimension of remaining gene expressions is 655. The dataset is used to illustrate the usage of the boost.graph and LDA.boost functions.
