WebNov 8, 2024 · This function expresses contrasts between a set of parameters as a numeric matrix. The parameters are usually the coefficients from a linear model fit, so the matrix specifies which comparisons between the coefficients are to be extracted from the fit. The output from this function is usually used as input to contrasts.fit . WebThe B-C contrast simply finds genes that are differentially expressed between B and C, nothing more and nothing less. The null hypothesis for B-C is that muB - muC = 0 where muB and muC are the expected log-expressions for the two groups. You can see that A cancels out just by elementary math: (B-A)- (C-A) = B - A - C + A = B - C + A - A = B - C.
