Real Time Remote Access (RTRA) outputs

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:

  1. Customized SAS Log (.log) – Contains all elements of a standard SAS log with the exception of the number of observation‚ which has been removed to protect confidentiality.
  2. Real Time Remote Access (RTRA) log created from the Real Time Remote Access (RTRA) system (.txt) – Informs users about which stage of the Real Time Remote Access (RTRA) process the SAS program has successfully completed.
  3. SAS datasets (.sas7bdat) – Contains output results in SAS dataset format.
  4. Table (.csv) – Contains output results in comma-separated values format.
  5. Tables (.html) – Contains output results in HTML format.

Users may receive the following message when accessing output in SAS dataset format:

Note: Data file LIBA.RTRA961628_TABLE1.DATA is in a format that is native to another host‚ or the file encoding does not match the session encoding. Cross Environment Data Access will be used‚ which might require additional CPU resources and might reduce performance.

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:

Data LIBA.RTRA961628_TABLE1;

Quality indicators

RTRA system will provide users with indicators of data quality for surveys that have bootstrap weights associated with the files. For statistics with quality indicators, the number of bootstrap weights used in its’ calculation is named “BSWCNT” in RTRA output.

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

Quality Indicators (Q.I.)
  • C.V. values are not released
  • Quality Indicators (Q.I.) are released based on the following C.V.1:
Value of coefficient of variation (C.V.) Quality indicator
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 (.)
Suppressed statistic (.)
