Online Analysis Using SDA

The online analysis system allows you to run both simple and complex analyses, recode and compute new variables, and subset variables or cases for downloading. The software powering the system, named Survey Documentation and Analysis (SDA), was developed by the Computer-assisted Survey Methods Program (CSM) at the University of California, Berkeley.

Weight

Please note that weights may affect analysis results.

(1) The data should be weighted for analysis. The appropriate weight variable is NFNWT from the original MIDUS survey (ICPSR 2760). The principal investigators recommend that users normalize the weight to produce an N of 724 before applying it to analyses. Part 1 of this data collection includes both the NFNWT weight variable and a normalized weight variable called WEIGHT. Please see the codebook notes for more information about the weight variables. (2) The original Part 1 data file from the principal investigators contained seven duplicate records. These records were dropped by ICPSR in order to create a unique record identifier to facilitate merging the weight variable from the main MIDUS data to the Part 1 data file.
