Table 5 Summarization of discretized data using ranks of gene expressons.

From: Improving the prediction accuracy in classification using the combined data sets by ranks of gene expressions

   Experimental groups by phenotypes

  1. The significant genes can be selected by independency test between the phenotypes and gene expressions using this type of summarized data set. c i ,r i represent the marginal sums of the ithcolumn and row, respectively. n represents total number of experiments. a: minimal entropy method
