Hands-On Workshop on WarpPLS; 11-12 January 2013; San Antonio, Texas

*** Two-Day Hands-On Workshop on WarpPLS: SEM Fundamentals with Linear and Nonlinear Applications ***

Structural equation modeling (SEM), or path analysis with latent variables, is one of the most general and comprehensive statistical analysis methods. Path analysis, multiple regression, ANCOVA, ANOVA and other widely used statistical analysis methods can be seen as special cases of SEM.

WarpPLS is a very user-friendly and powerful software tool that can be used for SEM, arguably being the first of its kind to implement linear and nonlinear algorithms. This software provides one of the most extensive sets of SEM outputs; among other things it is the first of its kind to automatically calculate indirect and total effects and respective P values, as well as to calculate full collinearity estimates.

This SEM fundamentals workshop (details below) is designed to be useful to beginners and intermediate SEM practitioners. Among possible participants are those who are interested in: (a) being productive co-authors or research collaborators, even if not doing SEM analyses themselves; (b) conducting basic SEM analyses occasionally in the future; (c) conducting SEM analyses of intermediate complexity on a regular basis.

*** Registration and additional details ***


*** Instructor ***

Ned Kock, Ph.D.
WarpPLS Developer

*** Location and dates ***

Our Lady of the Lake University
San Antonio, Texas
11-12 January 2013 (Fri-Sat), 8 am–5 pm

*** Workshop program at a glance ***

The main goal of this workshop is to give participants a practical understanding of how to use the software WarpPLS to conduct variance-based SEM. The workshop is very hands-on and covers linear and nonlinear applications.

New article discussing methodological issues based on WarpPLS: Exploring free questionnaire data with anchor variables

A new article discussing methodological issues based on WarpPLS is available. The article is titled “Exploring free questionnaire data with anchor variables: An illustration based on a study of IT in healthcare”. It has been recently published in the International Journal of Healthcare Information Systems and Informatics. See this post on the WarpPLS blog for more details and a link to a full text version of the article.

Version 3.0 of WarpPLS is coming soon, with several new features

Version 3.0 of WarpPLS is currently undergoing a battery of tests, and will be made available soon. Among the new features is the calculation of indirect and total effects, which are exemplified in this health data analysis post based on the China Study II dataset. Check this post for a comprehensive list of new features in this version.
