Sorry, I misunderstood your question.  Never having used -calibest-, I assumed that what you wanted to do is create the weights.

I have downloaded -calibest- from SSC. There is also a companion ado-file -calibrate- (on SSC) that creates the calibrated weights. In my case I have got a dataset with calibrated weights.  

I have tried egen with the group() extension but in that case all new subgroups (agegroup by sex) sum to 100%. I want to know the proportion of women in each agegroup (for example).

Tomas Lind:

Please give a link/source to the unofficial command -caibest- as the FAQ request.
To answer your question: create a combination variable that has age-gender categories.  
You can use  -egen- with the group() extention  or -groups-, by Nick Cox, available
from SSC, which will save a data set with the combinations.

Hi Statalist


Question about how to analyze survey data with calibrated weights.


There is an ado-file calibest that makes it possible to analyze survey data with calibrated weights (ref below). However, it seems impossibly to use calibest to calculate mean values and proportions for men and women _subdivided_ on agegroups (for example). Like you usually do using -over()- or -by- options. 

Is there a way around this problem?


Yours
Tomas Lind


I´m using Stata 11 on a PC.
