This variable is contained in the following files:
SAS Name
SAMPLE_GRP
This variable is designed to identify 1% random sample of beneficiaries. CCW creates a stratified random sample by state (variable called STATE_CD) and Medicare-Medicaid Enrollee Type (variable called MME_TYPE_CD). CCW designed the sample so that it is representative of each state’s data in MMLEADS, and within the state it is representative of the underlying distribution of MME_TYPE_CD.
| Code | Code value |
|---|---|
| 0 | Not included in sample |
| 1 | Included in 1% sample |
Since the MMLEADS files are very large, CCW developed this variable and includes it in MMLEADS as a simple way to test analytic code — or conduct exploratory analyses using a small subset of data.
