Cindy, I agree with the one other reply so far. This is really a case where we need to know much more about the project. What is the question? What is the data, Where does the data come from? Etc. You will get much more help if you spell it out for us. I have worked with LOS data, but I have no idea what you are doing.
Best wishes,
Nayak
