This is the explanation for SPSS "you will see a statistic called −2 log likelihood (which we will abbreviate as −2LL), which is a generally a measure of *lack of fit, *or *error variation*, and is conceptually the opposite of *R*2 in regression". I am wondering how to get the -2LL in JMP.

I am having a statistics class, and I am the only student using JMP. I am so confident with the JMP user community. JMP is my favorite!
