Dear Prof., My syntax of LPA was as followed: "TITLE: ; DATA: FILE IS parent and school.dat; VARIABLE: NAMES ARE SCHID STUID x1-x4 y1-y3 z1-z4 w; USEVARIABLES = x1-x4 z1-z4; WEIGHT = ; MISSING ARE ALL (9997 9998 9999); CLASSES = c (3); CATEGORICAL = ; AUXILIARY = ; ANALYSIS: TYPE = MIXTURE; OUTPUT: TECH1 TECH7 TECH10 TECH11 TECH14;"
Mplus can output p value of BLRT,but also gives the warnning like: " WARNING: THE BEST LOGLIKELIHOOD VALUE FOR THE 2 CLASS MODEL FOR THE GENERATED DATA WAS NOT REPLICATED IN 3 OUT OF 5 BOOTSTRAP DRAWS. THE P-VALUE MAY NOT BE TRUSTWORTHY DUE TO LOCAL MAXIMA. INCREASE THE NUMBER OF RANDOM STARTS USING THE LRTSTARTS OPTION."
So how can I change the syntax to get a trustworthy BLRT? Can you give a example about the syntax?
