Property Value
Type:
Int32
An
int array containing the levels of entry into the model for
each variable.
Remarks
Each variable is assigned a positive value which indicates its level
of entry into the model. A variable can enter the model only after
all variables with smaller nonzero levels of entry have entered.
Similarly, a variable can only leave the model after all variables
with higher levels of entry have left. Variables with the same level
of entry compete for entry (deletion) at each step. A value
Levels[i]=0 means the
i-th variable never enters the
model. A value
Levels[i]=-1 means the
i-th variable is
the dependent variable. The last element in
Levels must
correspond to the dependent variable, except when the
variance-covariance or sum-of-squares and crossproducts matrix is
supplied.
By default, Levels = {1, 1, ..., 1, -1}, where -1 corresponds
to the dependent variable.
