EQS 6.3 Build 115 implements 1) robust information matrix for LMTEST when METHOD=ML,ROBUST is used.  2) implements Savalei & Falk (2014) Two-Stage approach with incomplete non-normal data.  The command is MISSING=TS,ROBUST;  The download file bears the name of SetupEQS63D.exe

EQS 6.3 Build 114 fixes standard error problems in multisample analysis robust estimation.  The download file bears the name of SetupEQS63C.exe

EQS 6.3 Add Exploratory Factor Analysis in its command user interface under EFA menu.  A new addition of Parallel Analysis for factor retention is included in the EFA function.  This version also include AIC and BIC based on log likelihood (raw data input ins required).  It is currently a trial version only.  The EQS 6.3 is independent from EQS 6.1 and EQS 6.2.  Its installation will not affect previous versions.  Any users who has a valid EQS license number can download and install this version.

EQS 6.2 Build 107 fixes a bug on Diagrammer.  When you create a model with Diagrammer and choose AGLS as estimation method.  There is an error passing the outcome to the Diagrammer.  This problem has been fixed.  This is the only change in the program.  If you have categorical variable and any category is less then 4% of the sample, the previous build will stop the program.  Current implementation allows you to proceed but a warning message is printed.

EQS 6.2 Build 105 fixes a bug on reading ETS file.  For those who running simulation should download this version for ETS file is essential for secondary analysis of simulation outcome.

For those who downloaded EQS 6.2 Build 104 prior to May 16, 2013, please install EQS 6.2 again. There is an error in combining categorical and continuous variables. It is fixed.

Works with all Windows Operating Systems.  Electronic versions of the User's Guide and a partial draft of the Program Manual are available in the help files.  Build 86 uses a new way to export EQS output to Diagrammer.  It makes EQS model more readable.  You could also download a QuickStart, a PDF document provides a brief view of EQS.
