  • Statisical Anaysis

    Hello all,
    I am currently an undergrad Biomedical Engineer involved with a
    research project. In a nutshell, the project requires me to take a small
    amount of data (less than 20 items) and perform some statistical analysis on
    it. The data represents the success rate (the number of patients who
    remained in a medical study, and experienced a postive outcome) of a new
    surgical procedure over a two year period, broken down for each month over
    the period. What I need to do is to take the data and use it to prove that
    the surgical procedure is successful, compared to a control group of data in
    which the procedure was not performed. My problem lies in the fact that I
    need to first find, and then use some kind of software package(s?) that
    would allow me to do the analysis easily. In addition, I need some type of
    software that would plot the data points, and extrapolate an equation of a
    curve which would represent that data.
    As I have already mentioned, I am an undergrad at Rensselaer
    Polytechnic Institute (RPI) in New York, so I am somewhat constrained to
    work with the software available on the campus system. As far as I know,
    there are only 3 software packages available that are capable of doing any
    kind of statistal analysis at RPI. They are MS Excel under the MS Windows
    platform, and Xess and SAS on the Unix platform. As many of you already
    know, Excel is essentially a spreadsheet application. Xess, is to the best
    of my knowledge, a spreadsheet application, quite similar to Excel, on the
    Unix platform. SAS is a HUGE statisical analysis package, however, it is
    almost to large for me to use succesfully. I have attempted to figure out
    its complexities, and I keep getting lost in many windows and menus that it
    opens in the process. I would be very willing to use SAS, if I could figure
    out HOW to use it effectively.
    If anyone knows of some other software that can be purchased, or
    downloaded that would perform the tasks that I have, I would be happy to
    hear about them. I have Windows, MacOS, and UNIX platoforms available to
    me. In addition, if anyone is familiar enough with the packages that I
    currently have available to me, so that they could provide some assistance
    in using them, I would be very grateful as well.
    Please send all replies to me, and not to the list, as I don't want
    to waste disinterested peoples' time and bandwidth. As is the policy on
    this list, I will post all replies that I recieve to the list if I see that
    there is a significant interest. Thanks in advance for any assitance that
    you can provide to me.
