Wald Chi Square Table. How to use this table this table contains the critical values of the chi square distribution. 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.

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.
How to use this table this table contains the critical values of the chi square distribution. The p value is less than the generally used criterion of 0 05 so we are able to reject the null hypothesis indicating that the coefficients are not simultaneously.
