GLOR Subcommand (GENLOG command)

GLOR (Generalized Log-Odds Ratio) specifies the population contrast variable(s). For each variable specified, GENLOG tests the null hypothesis that the generalized log-odds ratio equals 0 and displays the Wald statistic and the confidence interval. You can specify the level of the confidence interval using the CIN significance-level keyword on CRITERIA. By default, the confidence level is 95%.

  • The variable sum is 0 for the loglinear model and for each combined level of independent variables for the logit model.
  • Variables specified as dependent or independent variables in the variable list cannot be specified on GLOR.
  • The coefficient is not applied on a case-by-case basis. The weighted mean for a cell is applied to that cell.
  • If multiple GLOR subcommands are specified, the last specification takes effect.

Example

GENLOG A B
 /GLOR=COEFF
 /DESIGN=A B.
  • The variable COEFF contains the coefficients of two dichotomous factors A and B.
  • If the weighted cell mean for COEFF is 1 when A equals B and –1 otherwise, this example tests whether the log-odds ratio equals 0, or in this case, whether variables A and B are independent.
