Summary of log-linear analysis designed to test the effects of maize tissue (ear versus shoot) and gene status (selected versus neutral) on e-northern gene expression data
Results are presented for e-northern analyses representing all libraries and nonnormalized libraries for the e-value criterion of 10−30. Degrees of freedom are the same for both tests of nonnormalized and complete libraries. Num DF, Numerator degrees of freedom. Den DF, Denominator degrees of freedom.
