Fitting Structural Equation Mixture Models (nlsem)
Estimation of structural equation models with nonlinear effects and underlying nonnormal distributions.

Tools for Detecting Influential Data in Mixed Effects Models (influence.ME)
influence.ME provides a collection of tools for detecting influential cases in generalized mixed effects models. It analyses models that were estimated using lme4. The basic rationale behind identifying influential data is that when iteratively single units are omitted from the data, models based on these data should not produce substantially different estimates. To standardize the assessment of how influential a (single group of) observation(s) is, several measures of influence are common practice, such as DFBETAS and Cook’s Distance. In addition, we provide a measure of percentage change of the fixed point estimates and a simple procedure to detect changing levels of significance.

Advanced Tables for Markdown/HTML (htmlTable)
A package for creating tables with state of the art layout containing row spanners, column spanners, table spanners, zebra striping, and more. While allowing advanced layout the underlying CSS structure is simple in order to maximize compatibility with MS Word/LibreOffice. The package also contains a few text formatting functions that help outputting text compatible with HTML/LaTeX.
