SURVEYMEANS Procedure


The SURVEYMEANS procedure estimates characteristics of a survey population by using statistics computed from a survey sample. It enables you to estimate statistics such as means, totals, proportions, quantiles, geometric means, and ratios. The following are highlights of the SURVEYMEANS procedure's features:

  • provides domain analysis, which computes estimates for subpopulations or domains
  • estimates variances and confidence limits and performs t tests for these statistics
  • computes variances of the parameters by using the following methods:
    • Taylor series (linearization)
    • balanced repeated replication (BRR)
    • delete-1 jackknife
  • enables you to employ Fay's method with BRR
  • performs poststratification
  • enables you to input or output a SAS data set containing a Hadamard matrix for BRR
  • enables you to import or export SAS data sets containing replicate weights for BRR or jackknife methods
  • creates a SAS data set that contains the jackknife coefficients
  • performs BY group processing, which enables you to obtain separate analyses on gouped observations (distinct from subpopulation analysis)
  • creates a SAS data set that corresponds to any output table
  • automatically creates graphs by using ODS graphics
