Abstract:
|
Census products and related programs use cell suppression to protect data that is sensitive to our respondents. A disclosure procedure is applied before any data goes out for publication. The underlining algorithm used is a network flow model. We will review the disclosure procedure and how well the model does. A question that always arises is "how is a near optimized solution to be determined to the Cell Suppression Problem (CSP)?" A new linear programming approach is used in this research. The algorithm is applied to Survey of Business Owners (SBO)'s Hispanic data and comparisons with the 2002 publications are made.
