The limma method was developed for log-ratios, not proportions, but we show the results using proportions for comparison. The first group of ten rows are the p-values and the second group is the t-statistics, for reference. In the original paper, the top 8 probes were selected using the maxT multiple testing procedure with using Welch t-statistics on in [12]. This selection is the first column, ranked 1 through 10. The p-values/t-statistics for the probes using and limma correspond to the first column, with their ranks shown. Using t-statistics with , the selection is similar to , but not identical, since probes ranked 8th and 9th switch places. Using limma with and , the selection begins to vary widely at the 7th probe.
