    • Jan 17
      • First homework: login in to remote2.webstore.illinois.edu BEFORE next class! If you have trouble send me email.
      • Introduction sessions to SAS will be given on Tuesday, January 24, 9-10am, rm 22 Education Building. Bring a laptop to the session and be sure that you can login to remote2.webstore.illinois.edu before the sesson.
      • A bit of help on homework 1--- you need to compute the angle between two vectors, say x and y, assuming that you have computed the length of x and y (i.e., Lx and Ly), the SAS code (with comments) for this would be
        cos_x_y = x`*y/(Lx*Ly);

        * compute inverse of cos and answer given in terms of radians;
        rad_x_y = arcos(cos_x_y);

        * create a scalar equal to pi;
        pi = constant('Pi');

        * convert radians to degrees;
        degree_x_y = (180/pi)*rad_x_y;

    • Computing: We will be running the SAS statistical software (SAS) using remote desktop to a university server. Here are the instructions: Instructions. MAC users will have to download a (free) version of the remote desktop application. Note that when you are asked for computer by the remote desktop program, "remote2.webstore.illinois.edu".

       

      There are a few things that you need before you can connect to the remote server:
      • Your computer must be hooked up to the internet. If you access the internet via campus wireless, home, hotel, Espresso Royal, or elsewhere).
      • You must have the remote desktop application. Those running windows already have it, but those using a MAC, then you will need to download remote desktop server software.
      • You must run the VPN software to get behind the UofI firewall. See VPN (Virtual Private Networking)
      • You must be registered for the class. If you reccently registered, you may not yet have permission to login.
