Negative binomial regression analysis - doubts output SPSS

[Student073]

Hi, I run a negative binomial regression analysis, and got the output on SPSS, but I don't know how to interpret some results, especially those related to goodness of fit. I've seen some studies usually take "log likelihood". Also, "Wald Chi-Square", but I didn't get this in my SPSS output (how can I obtain it???). Could anyone help me interpreting "log likelihood", "likelihood ratio Chi-Square" and "Wald Chi Square" values? Thanks a lot!!
