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.
One
wide
format data set is required to run the
Local Control
process. This data set must contain one column containing the dependent response
variable
, one column containing the treatment variable, and multiple columns to be used as
predictor
variables.
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.
