Updated (4/19/01) EXE Utilities are now available for fully automated use of LISREL 8 and EQS 5.6 with NORM. Click here for details:
LISREL (NORMLIS)
EQS (NORMEQS)
Mplus (v. 2 NORM-MPlus)
SPSS (NORMSPSS)
The following provide a new (not necessarily better) way to use SPSS regression
with NORM

ALPHNORM (Exploratory Data analysis:
Coefficient Alpha, and set up for SAS PROC FACTOR)
NOTE: ALPHNORM works in the DOS environment.
Summary: Alphnorm is a utility that works with the EM output
(EM.PRM) from Joe's NORM program (version 2.0x)
(1) The current version of ALPHNORM reads in the file EM.PRM, and allows the user
to perform Coefficient alpha (standardized)
with any subset of the variables for which EM was run. The output includes scale
alpha, along with alpha-if-item-deleted
based on the EM covariance matrix.
(2) ALPHNORM also writes out a covariance matrix that is readable with SAS,
along with the SAS code for reading the file in. Sample code for PROC FACTOR is
given, along with
sample code for PROC REG (use with caution because sample size is arbitrary).
(3) The utility also produces a covariance matrix (in 6F12.7 format) that is useful with
LISREL, EQS and other
programs. (this program produces a vector of means, then the full covariance matrix, both
in 6F12.7 format)
Revised (6/4/01) alphni4.exe version 1.04.
Single Precision version. Current limitations: 110 variables in
EM.PRM,
20 items per alpha analysis. This version does not exit
DOS at the conclusion of every run.
alphni3.exe
(version 1.03). This version does exit DOS after ever run, but may work
better in some
instances
