Dear Sir, I want to use Mplus to calculate composite reliability of a bi-factor model. I define the total score of the test, but Mplus told me it is a unknown variable. I would like to check what is wrong with the codes. INPUT INSTRUCTIONS TITLE: S2_BI-CFAconditionID10repID123; DATA: FILE IS S2_10_123.dat; VARIABLE: NAMES ARE x1-x16; DEFINE: VAR=SUM(x1-x16); MODEL: g@1; f1-f2@1; f1 by x1-x8*(l1-l8); f2 by x9-x16*(l9-l16); g by x1-x16*(l17-l32); g WITH f1-f2@0; f1 WITH f2@0; VAR(VARX); MODEL CONSTRAINT: New(U C1 C2 CR CR1 CR2 CR3 V1); V1=VARX*1; U=l17+l18+l19+l20+l21+l22+l23+l24+l25+l26+l27+l28+l29+l30+l31+l32; C1=l1+l2+l3+l4+l5+l6+l7+l8; C2=l9+l10+l11+l12+l13+l14+l15+l16; CR=U**2/V1; CR1=C1**2/V1; CR2=C2**2/V1; CR3=CR+CR1+CR2; OUTPUT: STDY TECH1 CINTERVAL; *** ERROR in MODEL command Unknown variables: VAR in line: VAR |

Say: Usev = x1-x16 var; |
