Users will be notified via e–mail when output is received in their EFT inbox. Users have 7 days to retrieve the files from the Electronic File Transfer system; after 7 days‚ the files will be deleted. Only output tables from the Real Time Remote Access (RTRA) macros will be returned and outputs with missing values will not be available.
For each successful SAS program submitted‚ four types of files will be returned to you:
- Customized SAS Log (.log)—contains all elements of a standard SAS log with the exception of observation counts‚ which have been removed to protect confidentiality.
- Real Time Remote Access (RTRA) log created from the RTRA system (.txt)—informs users about which stage of the RTRA process the SAS program has successfully completed.
- SAS datasets (.sas7bdat)—contains output results in SAS dataset format.
- Table (.csv)—contains output results in comma-separated values format.
- Tables (.html)—contains output results in HTML format ("RTRAFreq" macro only).
Users may receive the following message when accessing output in SAS dataset format:
This note means the file was created in an operating environment (e.g. 64–bit) that is different than your environment. You can eliminate this message by applying this data step to convert your SAS file:
RTRA system will provide users with indicators of data quality for surveys that have bootstrap weights associated with the files.
The following quality indicators and/or precision measures may be available (output may vary depending on the statistic being calculated and survey being used):
BSWCNT: Bootstrap Weighted Count (the number of bootstrap weights used in its calculation)
COUNT: Weighted Counts
S.E.: Standard Error (precision measure)
CILB: Confidence Interval Lower Bound (precision measure)
CIUB: Confidence Interval Upper Bound (precision measure)
QI: Quality Indicator
Researchers are responsible for ensuring the quality of their output. Notes on data quality and usage of data sets can be found in the Surveys and metadata webpage.
Data quality definitions
|Value of coefficient of variation (C.V.)||Quality indicator|
|1. C.V. values are calculated from original S.E. and original estimate values.
2. n stands for the number of observations and X is kept confidential and may vary per survey.
3. C.V. not defined refers to cases of division by zero (when released estimate = 0).
|C.V. ≤ 0.05||(a)|
|0.05 < C.V. ≤ 0.15||(b)|
|0.15 < C.V. ≤ 0.25||(c)|
|0.25 < C.V. ≤ 0.35||(d)|
|C.V. > 0.35 or n < X2||(e)|
|C.V. not defined3||(*)|
|Released frequency = 0||(.)|
