Remote Access

The remote access system, Analytic Data Retrieval by Email (ANDRE), allows researchers to communicate with an automated system via email to analyze RDC data. Remote access provides the convenience of performing analysis from any computer at any time but it has several limitations. 

• Remote access is designed for researchers who are proficient with SAS and SUDAAN. These are the only statistical packages available through ANDRE.

•  Users must register a secure university, government or corporate email address. Free or web-based email accounts cannot be used, even in forwarding mode.

• All users, regardless of access mode (on site or remote) must complete the proposal process and the three confidentially forms. 

Rules and Restrictions

Consider all of the rules and restrictions of the remote system along with your research needs before deciding to use it as your mode of access. 

Rules for Usage

SAS/SUDAAN Procedure Restrictions

• At  NO time will researchers be able to see individual data records (microdata). Researchers send SAS/SUDAAN code via email, and receive their output via email, without direct access to the data.

•  Remote  access researchers can use ONLY standard SAS and SUDAAN statistical procedures to carry  out their analyses. Macros are not allowed. If you wish to use other statistical software such as STATA, HLM, or SPSS, you must conduct your research on site.

• The remote access system CANNOT allow certain SAS/SUDAAN procedures. Please read the SAS/SUDAAN Procedure Restrictions.

• Output that poses a disclosure risk will be suppressed. Any cell that contains 5 or fewer observations will be suppressed. Additional cells or values may be suppressed to maintain confidentiality (complementary suppression).
