Analyze & Subset--Study No. 21560
Title: National Ambulatory Medical Care Survey, 2005
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.
Microdata file users should be fully aware of the importance of the "patient visit weight" (PATWT) and how it must be used. Information about the patient visit weight is presented in the codebook. If more information is needed, the staff of the Ambulatory Care Statistics Branch can be consulted by calling (301) 458-4600 during regular working hours. Prior to this data release, researchers could not make physician-level estimates with publicly available NAMCS data. For 2005, a new "physician weight" (PHYSWT) variable was added to the first record for each individual physician in the dataset.
If you're having trouble with SDA utilities, you may wish to consult the online help files for SDA users provided by the Computer-assisted Survey Methods Program (CSM) at the University of California, Berkeley.
