Hi,
Say I run a survey among 5 people asking if someone uses SAS. For each person I can assign weight to reflect importance of each person for the population. Now I want to obtain number of people in the population using SAS.
I run:
data have;
input id sas w;
datalines;
1 1 0.2
2 0 0.05
3 1 0.1
4 1 0.95
5 0 0.6
;
run;
proc surveyfreq data = have;
tables sas;
weight w;
run;
Could you tell me which number in the output gives me the answer? Is it 65.7895% * 5 (weighted percentage multiplied by total number of observations)?
EDIT: obviously 65.7895% * 5 is wrong. I meant 65.7895% * number of observations in the population
Best
That is correct (the edited value)..
