MAXORDER Subcommand (HILOGLINEAR command)

MAXORDER controls the maximum order of terms in the model estimated for subsequent designs. If MAXORDER is specified, HILOGLINEAR tests a model only with terms of that order or less.

  • MAXORDER specifies the highest-order term that will be considered for the next design. MAXORDER can thus be used to abbreviate computations for the BACKWARD method.
  • If the integer on MAXORDER is less than the number of factors, parameter estimates and measures of partial association are not available. Only the goodness of fit and the observed and expected frequencies are displayed.
  • You can use MAXORDER with backward elimination to find the best model with terms of a certain order or less. This is computationally much more efficient than eliminating terms from the saturated model.

Example

HILOGLINEAR V1 V2 V3(1,2)
  /MAXORDER=2
  /DESIGN=V1 V2 V3
  /DESIGN=V1*V2*V3.
  • HILOGLINEAR builds a 2 × 2 × 2 contingency table for V1, V2, and V3.
  • MAXORDER has no effect on the first DESIGN subcommand because the design requested considers only main effects.
  • MAXORDER restricts the terms in the model specified on the second DESIGN subcommand to two-way interactions and main effects.
