I try again - perhaps it is analysis of covariance with treatment
(thio,ultiva) as two categories and antime as covariate. On the basis of
such a model, is then the probability of GCS <= 12 larger with thio treatment
?
Dear friends, forgive me a simple question, possibly related to quantreg
but I failed to get it done and hope for basic instruction.
I have two sets of observed Glasgow coma scores at admission to ICU after
operation, and accompanying time of anesthesia (in hours).
Thio is cheap and perhaps old fashioned, and ultiva expensive and rapidly
terminated. The problem is to estimate the probability of GCS 12 or lower
on the two treatments after taking time of anesthesia into account (antime)
which is longer for thio. How would I do that in the best way ?
