Mini-MAX is a five percent cross-sectional national sample of the MAX files. The sample is stratified by 51 jurisdictions and by basis of eligibility (aged, disabled, children, and adults) among full beneficiaries and separately for restricted beneficiaries. CMS oversampled smaller states and smaller subpopulations to increase the precision of the estimates. They also removed variables that were less commonly used, redundant, or unreliable to reduce the file size.
To facilitate wider use of MAX, CMS contracted with Mathematica to convene a technical expert panel (TEP) and determine the feasibility of creating a sample file for MAX. This report describes the feasibility analysis and recommends the development of a “Mini-MAX” sample.
This file is only available for 2008 and will no longer be produced.
