Subject   st: weighting scores to use in a higher level analysis
Date   Thu, 25 Feb 2010 11:19:22 +1100

Dear Stata users,
We recently conducted a survey in a number of hospitals. For each hospital normally we got 1-4 responses from doctors. Now we want to do analysis at both doctor level and hospital level. For descriptive and exploratory analysis at the hospital level, we want to weight the scores from doctors by the inverse of the number of doctors within the same hospital. 
I understand for e.g. regression I could perhaps use 
reg y x, cl(hospitals) 
I wonder if you have other suggestions to implement the weighting as mentioned above for descriptive statistics and AVOVA etc. at the hospital level. 
I am new to Stata so please do not mind if my question is naïve.  Many thanks in advance.

Best regards, 
Hao
