Our best-known products include:
- The pioneering software for structural equation
modeling now includes statistical methods for complex survey data. Create path diagrams
in an easy to use interface and generate syntax directly
from the diagram. The latest LISREL for Windows includes
the following statistical applications.
- LISREL
for structural equation modeling.
- PRELIS
for data manipulations and basic statistical analyses.
- MULTILEV
for hierarchical linear and non-linear modeling.
- SURVEYGLIM
for generalized linear modeling.
- MAPGLIM
for generalized linear modeling for multilevel data.
- Hierarchical data modeling with power. The latest
version includes an improved interface, HTML output, and
new statistical features such as cross-classified random
effects for linear models for three-level data, and linear
and nonlinear models for four-level data.
- Mixed-effect
program that combines MIXREG, MIXOR, MIXNO and MIXPREG;
allows two- and three-level models. Easy to use graphical
user interface.
- Our group of item analysis programs
(BILOG-MG, IRTPRO, and PARSCALE) now feature friendly, new
Windows graphical user interfaces. They are all the tools
you will need to perform a wide variety of analyses on many
different types of tests and items.
