CRITERIA Subcommand (LOGLINEAR command)
CRITERIA
specifies the values of some constants in the Newton-Raphson algorithm.
Defaults or specifications remain in effect until overridden with
another CRITERIA
subcommand.
CONVERGE(n). Convergence criterion. Specify a value for the convergence criterion. The default is 0.001.
ITERATE(n). Maximum number of iterations. Specify the maximum number of iterations for the algorithm. The default number is 20.
DELTA(n). Cell delta
value. The value of delta is added to each cell frequency
for the first iteration. For saturated models, it remains in the cell.
The default value is 0.5. LOGLINEAR
does not display parameter estimates or correlation matrices of
parameter estimates if any sampling zero cells exist in the expected
table after delta is added. Parameter estimates and correlation matrices
can be displayed in the presence of structural zeros.
DEFAULT. Default values
are used. DEFAULT
can be used to reset the parameters to the default.
Example
LOGLINEAR DPREF(2,3) BY RACE ORIGIN CAMP(1,2)
/CRITERIA=ITERATION(50) CONVERGE(.0001).
-
ITERATION
increases the maximum number of iterations to 50. -
CONVERGE
lowers the convergence criterion to 0.0001.
