ECEN 689 - Statistical Computation in Genomic Signal Processing Fall 2009 Homework 3 Due on: October 28, at the start of class. Homework Policy : You are expected to write and code in a clean and documented style, and demonstrate that you understood the problem and its solution. You can discuss the problems with your colleagues if you wish but each student must code their own solutions separately. Late homework cannot be accepted, unless there is a documented valid reason. Please e-mail me a PDF with your answers and code in one PDF. Problems: 1. Suppose that for a given probe set, all the PM values are constant and euqal to α P , whereas all MM values are also constant and equal to α M . If α P α M then clearly the probe set will be called “absent” (A). If α P > α M , explain in detail what happens. Hint: You may find useful experimenting with the R function wilcox.test() , using the parameter alternative="greater" .
