Sample throughput, frequency of use, automation and the number of laboratories that would run the ...statistics but instead to find practical methods for analyzing data, a strong emphasis has been put on choice of appropriate standard statistical model and statistical inference methods (parametric, non-parametric, resampling methods) for different types of data. Then, methods for processing multivariate data are briefly reviewed. TheFinally, special statistical methods are applied to microarray and proteomics data, since the large number of genes or proteins evaluated increase the likelihood of false discoveries. Additional studies in separate samples are used to verify microarray and proteomic data. Examples in this chapter and references are available to help continued ...
