Wald Chi Square Table. Df 0 995 0 975 0 20 0 10 0 05 0 025 0 02 0 01 0 005 0 002 0 001. A wald chi square test based on the difference between observed and expected weighted cell frequencies and a wald log linear chi square test based on the log odds ratios.
Below the list of constraints we see the chi squared value generated by the wald test as well as the p value associated with a chi squared of 27 53 with two degrees of freedom.

Wald chi square test proc surveyfreq provides two wald chi square tests for independence of the row and column variables in a two way table.
Below the list of constraints we see the chi squared value generated by the wald test as well as the p value associated with a chi squared of 27 53 with two degrees of freedom.
If you use a 2 tailed test then you would compare each p value to your preselected value of alpha. If you use a 2 tailed test then you would compare each p value to your preselected value of alpha.
