I am from HEC Montreal university, where we start using Mplus. I have a problem with a multilevel model. Can you please look at the error below with my syntax? Thanks! variable: names = A1-A231; missing = all(-99); usevariables are A193 A194 A195 A196 A197 A198 A199 A202 A203 A204 A205 A228 A229; BETWEEN ARE A193 A194 A195 A196 A197 A198 A199 A202 A203 A204 A205; cluster = A1; DEFINE: CENTER A193 A194 A195 A196 A197 A198 A199 A202 A203 A204 A205 A228 A229 (GRANDMEAN); analysis: type = twolevel; model: %WITHIN% !

Check your data and format statement. Between Cluster ID with variation in this variable Variable (only one cluster ID will be listed) A193 3 A194 3 A195 3 A196 3 A197 3 A198 3 A199 3 A202 3 A203 3 A204 3 A205 3 |

Look at cluster 3 and see if the variables A193-A205 have variation within that cluster. If they do, they are not Between variables as you have specified. |

Thanks for your rapid answer. Maybe my understanding isn't clear, but what means "having variation within a cluster? It means that, for example, in cluster 3, all answers to A193 should be the same for all my respondants in Cluster 3? |

That's right. If the variable values are not the same for all respondents in the cluster, then the variable is not a between variable, that is, it varies not only across clusters but also within. |

Thanks. I tried and the error was gone. One thing i don't understand now. How can i test a level 2 variable impact on a level 1 variable. Exemple, Supervisor Support at Group Level impact on Satisfaction at individual level. I seem to be able to test on one level, Mplus ask me to chose one or another? If you look this syntax, i want to test Lmxb on HUMSUPN. analysis: type = twolevel; %WITHIN% ! Model for Within effects follows LMXw by A228 A229; ! LMX is a factor defined by A228 and A229 %BETWEEN% ! Model for Within effects follows LMXb by A228 A229; ! LMX is a factor defined by A228 and A229 %WITHIN% HUMSUPN by A194 A196 A199 A203; %BETWEEN% ! Model for Between effects follows HUMSUPNb by A194 A196 A199 A203; %BETWEEN% LMXb on HUMSUPNw; output: sampstat stdyx ; |

See Example 9.2. You need a random slope for a cross-level interaction. |

Thanks. Can you explain me what is the variable "w" in Example 9.2 Thanks for your time. |

A between-level covariate. |
