[R] how to install yags in R

[Tu Yu-Kang]

Dear R users,

I search the R archives and noted that the same problem has been posted but 
without solution.

I know there IS instructions by the author of yags, but I just couldn't 
figured out.

I know gee and geepack can also perform generalized estimating equation, 
but the reason why I need yags is I want to perform a Small Sample 
Adjustments by Michael P. Fay and Barry I. Graubard in Biometrics, 2001, 
57: 1198-1206.

I'm working on some dental data (I'm a dentist) with repeat measurements on 
relatively small sample sizes (around 20 to 50 teeth), and GEE seems to be 
quite ineffient (i.e. less powerful) compared to other methods.

I wonder it is really due to the sample size is too small, and GEE should 
not be used?

Many thanks in advance.

best regards,

Yu-Kang
