解决方法:可以采用SPSS对X1进行频率分析,查看X1这个变量的值是否存在非整数,如果是,可将其转换为整数。 Error 3 错误提示:ERROR in DEFINE command: Error in assignment statement for X. 可能原因:在DEFINE中使用了BY定义潜变量,如下图所示。 解决方法:定义潜变量的语句应放在MODEL部分 Error 4 错误提示:Categori...
*** ERROR in DEFINE command Error in assignment statement for CENTER Could you please help. The syntax seems to be right so I am guessing I can't centre these variables for some reason. Thanks in advance for your time. Best regards, Kirill Linda K. Muthen posted on Thursday, May...
I am assessing longitudinal mediation. I am new to MPLUS and am in need of some advice/guidance to make sure my code is correct & that my models include everything they should (and should not). I have 3 time points (1,2,3), X=intervention group assignment, M=mediator, and Y= out...
I am doing manual 3-step of GMM with Type=Imputation (I am using 10 sets of multiplely imputed data).I've got the 3 class model in step 1. Now I'm wondering (1) how to get class assignment. As far as I understand, I need to obtain 10 sets of data file that contains class ...
Ultimately class assignment will be entered as the first block in a HMR, with demos in a second block, to examine relationship with father involvement attitudes. Alternative plan: Conduct an LCA using sexism scores as y's and the demos as u's. After selecting the best fitting model, ...
I am conducting LCA. But I keep receiving the following error message: THE STANDARD ERRORS OF THE MODEL PARAMETER ESTIMATES MAY NOT BE TRUSTWORTHY FOR SOME PARAMETERS DUE TO A NON-POSITIVE DEFINITE FIRST-ORDER DERIVATIVE PRODUCT MATRIX. THIS MAY BE DUE TO THE STARTING ...
It is randomization assignment/study arm assignment (0 = control; 1 = intervention). I suppose I should've called it X for consistency with the way such variables are described in the Mplus documentation and related literature. M and Y are repeated 5 times. By the way, I really ...
If you calculate Vermunt's D-matrix (the flipside of Mplus' classification table) for the two approaches then the one for modal-class is better in terms of the magnitude of the probabilities on the main diagonal compared with proportional assignment. I was initially shocked to discover this ma...
I've modeled the largest dependency using type=complex, parameterization=rescov, and the "with" statement in the model. Now I'd like to generate new data and get new bootstrapped p-values for the BVRs, having modeled one local dependence. I'm having trouble, however, figuring out how...
I also checked that there is variance in each of my classes for my three distals using the most likely class assignment. However, I still am not able to test the equality of means using "model test." Is there a different way for testing the equality of means in the context of the ...
