Summary of survey software:
Stata
Vendor
StataCorp
Types of designs that can be accommodated.
- stratified designs;
- cluster sampling;
- variance estimation for multistage sample data can be carried
out through the customary between-PSU-squared-differences
calculation;
- finite-population corrections can be calculated for simple
random sampling without replacement of sampling units within
strata.
Types of estimands and statistical analyses that can be accommodated.
There are about currently about 20 Stata commands for various analyses
of survey data, including the following analyses and others:
- Estimation of means, totals, ratios, and proportions.
- Linear regression, logistic regression, and probit; also, tobit,
interval, censored, instrumental variables, multinomial logit, ordered
logit and probit, and Poisson. Point estimates, associated standard
errors, confidence intervals, and design effects for the full population
or subpopulations are displayed. Auxiliary commands will display all
this information for linear combinations (e.g., differences) of
estimators, and conduct hypothesis tests.
- Contingency tables with Rao-Scott corrections of
chi-squared tests; new survey-corrected regression commands including
tobit, interval, censored, instrumental variables, multinomial logit,
ordered logit and probit, and Poisson.
Restrictions on number of variables or observations.
Maximum number of observations limited only by computer RAM (virtual
memory can be used, but commands run slower). Maximum number of
variables is 32,767 with Stata/SE and 2047 with Intercooled Stata.
Primary methods used for variance estimation.
Taylor-series linearization is used in the survey analysis commands.
There are also commands for jackknife and bootstrap variance estimation;
although these are not specifically oriented to survey data they will
accomodate survey features like clustering and stratification.
General description of the "feel" of the software.
Stata is a complete statistical software package with full statistical,
data management, and graphical capabilities. It can be run
interactively or in batch mode, and is fully programmable. The
survey commands are part of the standard software package.
Initially, data can be read in from ASCII files and a Stata-format
data file created; or data in other file formats can be translated
to Stata format using a stand-alone software package (Stat/Transfer
or DBMS/Copy).
Platforms on which the software can be run.
- Windows (all current versions);
- Power Macintosh (OS X 10.1 or later);
- Alpha AXP running Digital Unix;
- HP-9000 with HP-UX;
- Intel Pentium with Linux (32-bit);
- RS/6000 running AIX;
- SGI running Irix 6.5;
- SPARC running Solaris (64-bit and 32-bit).
- Linux 64
Software distributed as precompiled object program.
