Details

For categorical and logical variables, presents the estimated counts, their standard errors (SEs) and confidence intervals (CIs), percentages, and their SEs and CIs. Checks the presentation guidelines for counts and percentages and flags estimates if, according to the guidelines, they should be suppressed, footnoted, or reviewed by an analyst.

For numeric variables, presents the percentage of observations with known values, the mean of known values, the standard error of the mean (SEM), and the standard deviation (SD).

CIs are calculated at the 95% confidence level. CIs for count estimates are the log Student's t CIs, with adaptations for complex surveys. CIs for percentage estimates are the Korn and Graubard CIs.
