Local Control estimates treatment effects within clusters of subjects as described in Lopiano, Obenchain and Young (2014)
1. You can use this process interactively to select the number of clusters and cumulatively compare results. This kind of analysis is useful for handling subgroups in observational or experimental data.
The adsl_dii.sas7bdat data set, partially shown below, details results for 902 subjects. Subjects are listed in rows, demographic information, trial details, and findings and results are listed in columns. The
ARM column lists the treatment variable. The
DEATHFL column lists the
dependent variable. The predictor variables are spread across 310 columns.
Refer to the Local Control output documentation for detailed descriptions of the output and guides to interpreting your results.
