Unformatted text preview: 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" ....
