Genetics Analysis in Mplus

With the introduction of Mplus Version 4, Mplus has greatly expanded its capabilities for genetics analysis. To show these capabilities, a set of Mx genetics examples from the GenomEUtwin project has been translated to Mplus. They can be accessed in the Examples section for Genetics Analysis using Mplus. In addition, the Mplus User’s Guide contains several genetics examples as shown below.

Twin, Sibling, and Family Genetics Modeling in the Mplus User's Guide

Two-group twin model for continuous outcomes where factors represent the ACE components (Ex. 5.18)

Two-group twin model for categorical outcomes where factors represent the ACE components (Ex. 5.19)

Two-group twin model for continuous outcomes using parameter constraints (Ex. 5.21)

Two-group twin model for categorical outcomes using parameter constraints (Ex. 5.22)

QTL sibling model for a continuous outcome using parameter constraints (Ex. 5.23)

Two-group twin model for categorical outcomes using maximum likelihood and parameter constraints (Ex. 7.28)

Two-group IRT twin model for factors with categorical factor indicators using parameter constraints (Ex. 7.29)

The example numbers in parentheses refer to the Version 5 Mplus User's Guide where these features are described.

The page numbers in parentheses refer to the pages in the Version 5 Mplus User's Guide where these features are described.
