when is a gene differentially expressed why would the false discovery rule be applied on the mann-whitney u test when does mann-whitney u test apply what is the test for differential expression in a microarray why is a false discovery test done at the data acquisition level when should the false discovery rate be controlled what is the statistical test for differentially expressed genes at what level of data acquisition, false discovery control and analysis should be applied? what is false discovery control at mann-whitney why do you need false discovery in your analysis? fdr should be controlled at the data acquisition level what is the test for false discovery which test is a false discovery control test? why should the false discovery process be applied why fdr for gene expression analysis is low why does the u test test false discovery what is the fdr level in gene expression what is the correct way of controlling false discovery? what is the false discovery level of gene expression how to determine differential expression
