Each Tuesday (Thursday, if there is no class on Tuesday) you must submit the solution of one problem from the list of theoretical problems for that week's topic. No credit for late solutions.

You should use statistical packages (SAS, C+ or similar) to solve the applied problems. It is assumed that you are familiar with at least one package. The solutions must be submitted as reports. This means that they are typed, the problems and the solutions are clearly explained. All figures and tables must be done on the computer.
