TABLE 4.

Results from study implementing GCC sampling on AHEAD data with number of instrumental activities of daily living as response. Below we show estimated coefficients and estimated standard error from the full data. We also show estimated coefficients with estimated standard error under SPGLM and GLM-based analyses implementing the GCC sampling plan from Table 3
