Dear Sir,
I am doing some work on a population of patients. About half of them are
admitted into hospital with albumin levels less than 33. The other half have
albumin levels greater than 33, so I stratify them into 2 groups, x and y
respectively.
I suspect that the average length of stay in hospital for the group of
patients (x) with albumin levels less than 33 is greater than those with
albumin levels greater than 33 (y).
What command function do I use (assuming that I will be using the chi
square test) to show that the length of stay in hospital of those in group x is
statistically significantly different from those in group y?
I look forward to your thoughts.
