1	Open	No
The Railroad Retirement Board's Bureau of Actuary should improve its documentation of the sampling employed in the Financial Interchange process by: Creating a single document that explains the process used to create the sampling frame and sample, including source database(s) used, the variables of interest, and the programs/media used to execute the process steps. The documentation should be written such that a person with the requisite skills, but without knowledge of the Financial Interchange calculations, could understand and replicate the sampling process.

The Railroad Retirement Board's Bureau of Actuary should test more than one post-stratification method and employ the method that minimizes the sampling error.
