I am estimating multilevel, weighted, continuous time survival models and the predictor variables of interest is on the WITHIN level. However, I am unable to create plots for each level of the variable. Is this possible in the current release?
They are part of PLOT2. However, when I attempt to specify the 'Estimated log cumulative curve' plots, I am able to use any of the plots in the 'Simple Curves' and 'Curves to Compare', but the 'Curves for specific covariate values' causes the program to crash.
I'm running a two level continuous time survival analysis with Mplus Version 6.11 as shown in example 9.18, specifying the PLOT2 option.
After selecting "estimated survival curve" under the "curves for specific covariate values" option, I am only able to select my time to event information variable t under "select the variable to be plotted". None of my covariates shows up here.
What do I have to do in order to select any of my covariates?
I am also trying to build up on example 9.18 and have two questions on that: 1) I like to calculate U^2 (Hauser 1978) and wonder how to modifiy the Mplus code of example 9.18 to get the log likelihood value of the null model. 2) How do I integrate time-varying covariatess on both levels in this analysis?
Is it possible to extend the discrete survival model (example 6.20/6.21) to a multilevel model? If so, I would highly appreciate if you could give me a hint how an exemplary Mplus code would look like. Would it be possible to include time-varying as well as time-invariant covariates on both, level 1 and 2?
