Gene Expression Data from Tumoral and Normal Prostate Samples and Labels
Normalized subset from Singh et al. (2002) data included in the prostate dataset. The raw data comprise the expression of 52 tumoral and 50 non-tumoral prostate samples, obtained using the Affymetrix technology. The data were preprocessed by setting thresholds at 10 and 16000 units, excluding genes whose expression varied less than 5-fold relatively or less than 500 units absolutely between the sample, applying a base 10 logarithmic transformation, and standardising each experiment to zero mean and unit variance across the genes. The 100 most variable genes were selected following the B/W criterion (Dudoit et al. (2002)) and a random selection of 25 normal samples and 25 tumour samples was performed.
