Hello everyone.
I am using logistic regression in the analysis of a database coming from
a study in Zimbabwe. A sample command is 'xi:logistic hiv i.age3 sexc
age'
The variable age3 is the age in 3 strata (2-4yrs, 5-11yrs, 12-17yrs). As
I currently have the coding, 0=2-4yrs, 1=5-11yrs, and 2=12-17yrs. Thus
the strata 2-4yrs is the point of comparison. In this case, the two
older strata both showed a reduced risk of infection.
However, I prefer to report the data in the context of which strata has
increased risk of infection. Is there a command I can use (or add to the
existing command 'xi:logistic hiv i.age3 sexc age') that would allow me
to change the order of strata during logistic analysis. That is to say,
if I want to use the 12-17 yr strata as the point of
comparison...without having to create a new variable in which I change
the coding.
Thank you
Todd
