Webin statistics, dating back to the classic Fisher’s combination test. In modern large-scale data analysis, correlation and sparsity are common features and e cient computation is a necessary requirement for dealing with massive data. To overcome these challenges, we propose a new test that takes advantage of the Cauchy distribution. Web1 is then a valid combination test. The Fisher Combination Test is an example of this; ﬁrst, we map ponto the positive real line by the mapping p7!2 P i2I logp i, which is then transformed back onto the unit interval using the CDF of a ˜2 2jIj-distribution. Another simple way of constructing valid combination tests is to use the minimal p-value WebFeb 11, 2015 · The ultimate goal here is to perform pair-wise fisher tests (using fisher.test ()) on each column and row between each of the data.frames.
