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 R2 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!
