Statistical Analysis of Efficient Unbalanced Factorial Designs for Two-Color Microarray Experiments [PDF]

International Journal of Plant Genomics, 2008
Experimental designs that efficiently embed a fixed effects treatment structure within a random effects design structure typically require a mixed-model approach to data analyses. Although mixed model software tailored for the analysis of two-color microarray data is increasingly available, much of this software is generally not capable of correctly ...
