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.
