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.
