Dear all,

I am not sure if this has been reported but when I use
-svytotal- in Stata 8.2, the saved results do not
match the output:

.  svytotal nons

Survey total estimation

pweight:  discwt                                 
Number of obs    =   7521922
Strata:   stratum                                
Number of strata =       623
PSU:      hospid                                 
Number of PSUs   =     10394
                                                 
Population size  =  37192136

                 r(N) =  7521922
          r(N_strata) =  1
             r(N_psu) =  7521922
             r(N_pop) =  7521922
          r(estimate) =  .9987735847300729
               r(Var) =  1.62845525174e-10
           r(Var_srs) =  1.62845525165e-10
           r(errcode) =  0

-svytotal- report a population estimate of over 37
million and saved results r(estimate) is less than 1.
What am I missing?

Thank you,
Ricardo.
