#### AMOS

AMOS is used for modeling linear structural relations among latent (unobserved) and manifest (observed) variables. You can use this software to estimate structural equation models (SEMs), exploratory and confirmatory factor analyses, and path analyses. AMOS features an intuitive graphical-user interface and superior handling of missing data.

The GradPack Versions 23, 24, and 25 are available at the following location:

HLM

HLM stands for Hierarchical Linear Modeling, the modeling of data arising from clustered populations such as students nested within classrooms nested within schools. While other software products contain facilities to handle clustered data to a greater or (more often) lesser extent, HLM was explicitly designed to fit linear and non-linear models to such data.

JMP

JMP is produced by SAS and offers most of the statistical analyses that SAS does but in an interactive mode. JMP is user-friendly in that it uses dialog boxes and allows you to interact with your data and output. JMP can "talk" to SAS using the JMP language if SAS is available on the machine.

JMP is available at the following location:

JMP Technical Support provides a list of FAQs, White Papers, and Webcasts to help you learn the software.

LISREL

LISREL and its data pre-processing companion PRELIS are used for modeling linear structural relations among latent (unobserved) and manifest (observed) variables. You can use this software to estimate structural equation models (SEMs), exploratory and confirmatory factor analyses, and path analyses. LISREL is well-suited to fitting large, complex models.

Minitab

Once used mostly for instructional purposes, Minitab has upgraded its software to make it more user-friendly and useful for the researcher while simultaneously keeping the small disk space and RAM requirements that has made it a favorite with instructors.

Versions 15 and 16 are available at the following location:

- e-academy lease licenses - 6 mo, 12 mo, or perpetual student license

MINITAB's Answers website provides a list of the most frequently asked support questions and their answers.

Mplus

Mplus is used for modeling linear structural relations among latent (unobserved) and manifest (observed) variables. You can use this software to estimate structural equation models (SEMs), exploratory and confirmatory factor analyses, and path analyses. Mplus is useful for databases with categorical outcome variables and clustered or hierarchical data (multilevel models).

SUDAAN

SUDAAN is a program designed to perform analyses of clustered (hierarchically structured) data or responses obtained via non-random sampling processes. Unlike hierarchical linear modeling programs such as HLM, SUDAAN allows investigators to consider sampling weights and data clustering simultaneously. It has two distinct versions: A stand-alone version and a SAS-callable version. The SAS-callable version allows SAS users to run SUDAAN procedures directly within SAS, a useful feature.
