Subject:      Prox Mix

Hello everyone.  I am hoping someone here can point me in the right
direction.
    I have to run an analysis to see changes in scores over age.  I have
3 cohorts (one has boys with ages 6-11, another has boys 9-14, and another
has boys
12-18) who were assessed for a series of years.  Across age (from 6 to 18)
there are cells that are empty for
particular cohorts, and the cell sizes change radically for the end ages
(e.g. for the 6-11 group, there are less boys who reach 6 to 11 than who
are at ages in between).  At first I was told to use BMDP 5v, but now
another person recommended HLM or a SAS program he thought was called
Prox Mix.
     Can anyone tell me if Proc Mix is the appropriate procedure and/or
send me a sample command file?  I have rarely used SAS in the past, but
have been wanting to learn.  I would like to know of a good source for
this procedure as well (I have SAS/STat User Guide books and sAS language
books but didn't seem to see this command in there).  I will be doing the
analysis on UNIX.
 
   Thank you, Laura Schmidt
