lavaan.survey
Take into account survey weights, clustering, strata, and finite sampling corrections in structural equation modeling analyses in R.
An R package allowing for complex sampling analysis of SEM in R using the lavaan and survey packages. Uses the Satorra-Bentler approach to multivariate complex sample analysis described in Muthén & Satorra (1995, Sociological methodology).
Thanks to the features written by Thomas Lumley in the survey package, lavaan.survey has features novel to SEM. For example, it allows for a finite population correction, and you can do GREG estimation of SEM models.

SQP 2.0
A new program for the prediction of reliability and method effect of a survey question. The prediction is based on characteristics of the question, such as its linguistic complexity, the number of scale points, presence/absence of a “don’t know” option, etc. See the report on my publications list for more information.
- Won the 2014 Warren J. Mitofsky Innovators Award from the American Association of Public Opinion Research (AAPOR)
- Described in the Wiley book “Design, Evaluation, and Analysis of Questionnaires for Survey Research, Second Edition” (Saris & Gallhofer 2014)
Registration and use of the program is open to all and free at http://sqp.upf.edu/.
