Dear Stata users and (self-confessed not-so-nice) Guru's
I've searched around the Stata resources for some time now but
haven't been able to find a solution for my problem (which I hope
isn't a FAQ, or perhaps even RTFM).
I'm doing statistics on an animal experiment that I've just finished.
Tumor bearing mice were submitted to different treatments ordered
into treatment groups. Respons to treatment was quantified by
measuring tumor size daily, however not in weekends. Tumor (implanted
subqutaneously in the foot) size was measured as length, breadth and
height, and the volume calculated as length*hight*breadth*\pi/6. I
haven't been able to find a satisfactory way to enter this data into
a Stata dta file. I'd like to be able to enter a data point as a 3-d
vector, but I don't know how, since this isn't a data type. My
current solution is to enter each measurement as a text string:
"ll,hh,bb" and then extract each parameter when needed. Is there a
Also, is it possible to define a 'class' or 'object' as a data type
(couldn't find anything appropriate in the 'Programming' manual)
called Mouse containing all this kind of information (mouse number,
group number, treatment date, daily sizes, etc.)?
