The SAS version I'm using is 2016, 9.4 (TS1M6), SAS/STAT 15.1 I am doing an exploratory factor analysis and confirmatory factor analysis with 16 binary variables and keep getting this error for the confirmatory factor analysis (proc calis): NOTE: Convergence criterion (GCONV=1E-8) satisfied. ERROR: Message file "t0l8en" is not found. NOTE: The data set MUR.OSTAT has 79 observations and 23 variables. NOTE: PROCEDURE CALIS used (Total process time): real time 2.61 seconds cpu time 0.15 seconds Any ideas how to address this error? I just can't find anything on it. Just in case it helps, here's my code. This is one way I ran it, I ran it a second way and had the same error with some additional warnings (below): Proc calis data=mur.ms_medical_history3 outstat=mur.ostat; lineqs A1ATTENTIONMEMORYrc = p1 fONE + e1, A1DIZZINESsrc=p2 fONE + e2, A1DOUBLEVISIONrc = p3 fONE + e3, A1EYEDISCOMFORTrc = p4 fONE + e4, A1FATIGUErc = p5 fONE + e5, A1SLURREDSPEECHrc = p6 fONE + e6, A1WALKINGrc = p7 fTWO + e7, A1MOVINGLIMBsrc=p8 fTWO + e8, A1LOSSBALANCErc = p9 fTWO + e9, A1COORDINATIONrc = p10 fTWO + e10, A1WEAKNESSLIMBsrc=p11 fTWO + e11, A1MUSCLESPASMsrc=p12 fTHR + e12, A1PAINMUSCLESPASMsrc=p13 fTHR + e13, A1NUMBNESsrc=p14 fFOU + e14, A1TINGLINGLIMBsrc=p15 fFOU + e15, A1VISIONLOSsrc=p16 fFOU + e16; STD e1-e16 = vare1-vare16, fONE fTWO fTHR fFOU = 1 1 1 1; COV fONE fTWO = COV12, fONE fTHR = COV13, fONE fFOU = COV14, fTWO fTHR = COV23, fTWO fFOU = COV24, fTHR fFOU = COV34; pathdiagram diagram=standard useerr; Run; Here is another way I ran it where I get the same error, with some additional warnings: From the log: NOTE: A utility disk data set is being used.
