    Question

    Two linear mixed models are used: an “empty” model with no fixed effect of time (2 parameters, -2Log-Likelihood=413.45), and a model with a linear fixed effect of time (3 parameters, -2Log-Likelihood=409.25).

    Perform a likelihood-ratio test to test whether there is a linear fixed effect of time.


    1. TRUE: χ2(df=1)=4.20;p<.05\chi^{2}(df = 1) = 4.20;\;p < .05
    2. FALSE: χ2(df=1)=4.20;p>.05\chi^{2}(df = 1) = 4.20;\;p > .05
    3. FALSE: χ2(df=3)=4.20;p<.05\chi^{2}(df = 3) = 4.20;\;p < .05
    4. FALSE: χ2(df=3)=4.20;p>.05\chi^{2}(df = 3) = 4.20;\;p > .05
