ESTIMATED CALCULATION OF SAMPLING

this is my problem, I have a database of lessons presidential, with variables, candidate 1, candidate 2, Total_ votes, Strata.

And what I want is to calculate the estimators of reason, or proportion between a candidate and the total votes, and estimate of the total votes cast, their corresponding variances and their corresponding deff.

My program is as follows:

DATA PREP2006;

RUN;

*STRATIFIED SAMPLING;

PROC SORT DATA=PREP2006 OUT=ORDER_PREP2006; BY STRATA;

RUN;

PROC SURVEYSELECT DATA=ORDER_PREP2006

OUT=WORK.SAMPLING METHOD=SRS N=3;

STRATA STRATA;

RUN;

PROC PRINT DATA=SAMPLING (OBS=10);

RUN;

*proportion between a candidate and the total votes;

PROC SURVEYMEANS DATA=SAMPLING;

    RATIO  CAN21 CAND2 / TOTAL_VOTES ;

RUN;

*ESTIMATED TOTAL VOTES ^T;

PROC SURVEYMEANS DATA=SAMPLING SUM VARSUM STD RANGE NMISS CVSUM CLSUM;

    VAR TOTAL_VOTOS;

    WEIGHT SAMPLINGWEIGHT;

RUN;

*THE FOLLOWING  PROC ME BACK THE DEFF, BUT NOT ON THE ESTIMATOR TOTAL OF TOTAL VOTES;

PROC SURVEYFREQ data=SAMPLING;

    TABLE TOTAL_VOTES / DEFF;

    strata ESTRATOS;

RUN;

HOW TO GET the following estimates?

    * estimates of population means and totals

    * estimates of population proportions

    * standard errors

    * confidence limits

    * deff For each ESTIMATOR

    * ratio estimates
