we hae a project to analyze the trends of a index. this index is produce with structrual equation modeling based on 24 variable. when calculating the index, we first divide those 24 variables into 5 groups, then use factor analysis to calculate the factor scores of every group, next step, use 4 groups factor scores to regress against the 5th groups factor scores and use the pridictive value as the index value.
Now we would like to analyze this index's trends with several years data?
I think every the index values should have autocorrelation error among different year.
Is it possiable to process this project with mplus?
