SPSS weicht davon etwas ab, indem dieses Quotient noch quadriert wird. Auf Basis dieser Wald-Statistik wird dann der p-Wert (L) berechnet. Für die Wald-Statistik ist noch wichtig zu wissen, dass diese manchmal verzerrt sein kann – der Chi-Quadrat-Test für den Omnibus-Test der Modellkoeffizienten hat dieses Problem jedoch nicht.

Wald is basically t² which is Chi-Square distributed with df=1. However, SPSS gives the significance levels of each coefficient. As we can see, only Apt1 is significant all other variables are not. If we change the method from Enter to Forward:Wald the quality of the logistic regression improves.

This table provides the regression coefficient , the Wald statistic (to test the statistical significance) and the all important Odds Ratio for each variable category. Looking first at the results for SEC, there is a highly significant overall effect (Wald=1283, df=7, p<.000). For these two tests, PROC SURVEYFREQ computes the generalized Wald chi-square statistic, the corresponding F statistic, and also an adjusted F statistic for tables larger than . Under the null hypothesis of independence, the Wald chi-square statistic approximately follows a chi-square distribution with ( R – 1)( C – 1) degrees of freedom for large samples.
