Title

gcsetup -- Specify the groups, variables, and labels for comparing groups in
regression models for binary outcomes.

Syntax

gcsetup varlist
,
grpvar(variable)
gr0var(new-variable)
gr1var(new-variable)
[
gr0label(string)
gr1label(string)
matrix(matrix-name)
details
]

varlist contains the independent variables that may be used as predictors
in later binary regression models.

Description

gcsetup names an existing variable that defines the two groups (hereafter grpvar);
names two groups indicator variables to be created from grpvar;
optionally provides short labels for the two groups and the name of a matrix to hold results;
and indicates the independent variables that will be used in later models.

Options

grpvar() names an existing variable defining groups. Value 0 indicates group 0, while
1 indicates group 1. This variable is referred to a grpvar below.

gr1var() is the name of variable to be created that equals 1 when grpvar is
1, 0 when grpvar is 0.

gr0var() is the name of variable to be created that equals 1 when grpvar is
0, 1 when grpvar is 0.

gr1label() is a string with a short label for the group defined by grpvar equal to 1.

gr0label() is a string with a short label for the group defined by grpvar equal to 0.

matrix() is the name of a matrix that will be created to hold the results when
gcprvalue is run.

details produces details on the variables and global variables that are created.
