Hello, My data is a longitudinal data. I am new in Mplus. It is too difficult to understand and fix the dataset and interpretaion. (1)Data format: FamID Sub ID Wave1 Wave2 Wave3 Wave4 Wave5... 1 1 0 0 0 0 1 2 0 0 1 1 1 3 0 0 1 0 2 1 0 1 0 0 2 2 0 0 0 0 2 3 0 0 0 1 2 4 0 0 0 0 3 1 0 1 1 1 3 2 0 0 1 1 3 3 0 0 0 1 3 4 0 0 0 1 4 1 0 0 1 1 ............................... (2)Data describe: (a)Family ID 1 have 3 Siblings. (b)Each siblings have response. About disorde present/absent in 4times. (c)family and sub Siblings have a strong correlate and sub ID and each wave have a strong correlate. (3)The aim: To consider they have a trend between Y (Disorder present or absent) and waves. Now, I consider two kinds of model. Like a Growth Curve model or Multilevel model. But not sure. Yes! I look the Ex9.13 (Version 3.12)But my dataset and this example dataset is different. Hopefully you can understand this thing. Could you give me your clear and good advice? * One more Question. I am really really new person in Mplus. So, even if I see the output, it is too difficult to me to understand. What's mean ...etcs., could you recommand something? I tried to read the Reference papers, but they still don't have enough explain about output. Seriously, need to help. Thank you so much. |

You are right that ex9.13 is a good example to follow. Your data structure suits this example. Your cluster variable ("CLUS = ") is family. Each cluster has 3 members (the 3 siblings). You have 5 u variables (5 time points). You have no x or w variables. To study this topic you can read books such as Raudenbush-Bryk or Boskers-Snijder and for Mplus-oriented material you can watch my multilevel web movie, or come to our short courses in Virginia in Nov. |

Thank you so much for your answer. I have more Questions. (1) You said, each cluster has 3 members. But, each cluster has the different members. But, is it fine?? (2) Yes! I don't have x and w variables. But, I confuse the define x and w variables. So, could you say to me about definition? Because, I think I wil must consider about the subject and waves relations. (3) If I still don't have a x and w variables, it is fine? (4) I can't fine the Raudenbush-Bryk or Boskersisnijer books. So,if it is not bother you, could you tell me the book name? (5) If I have a time, I will go this short courses. Thank you. |
