st: on-line resources for multiple partial F-test?

[Doug Mounce <mounce@u.washington.edu>]

Any recommendations for a good on-line description and explanation  
for applying the multiple partial F-test?  Also, what's the general  
way to think about using regress when the Y variable is continuous,  
but the X is binary?

We've been learning in class how to describe the regress of one  
continuous variable on another, and I understand how to do a log  
transform and look for curvature or heteroscedasticity.  We do  
jackknife residuals and some other diagnostics, and I'm stumped on  
how to describe the regress when the independent variable is binary.   
I can talk about the regression coefficient, I guess, but the R^2  
doesn't account-for much variation in this data.

Sorry if asking for help with homework is bad form, but I'm also have  
a lot of clinical data that's binary and I thought that regression  
was pretty limited there.  I'm an adult student with a job and family  
so finding a study group has been tough; any consideration of this  
request will be greatly appreciated, regards, Doug
