At developers meeting on 2/17 we discussed the following:
<
ul>
- The inclusion of coefficients and variables in a publication quality output of the model.
- Different views of a OpenMx model: (1) OpenMx source code, (2) modifiable graphical representation, (3) connector view.
- Model paths with good curvature.
- Provide the same features for RAM and LISREL models.
- OpenMx GUI - Timo von Oertzen is leading the development of this with several other of his colleagues. He will be meeting with them in several weeks to begin development.
- Weighted Least Squares Minimization - Ryne Eastbrook and Tim Brick are leading the development on this feature. The are investigating how to adapt some of the group's previous work to implement WLS in a new (and more documented) way.
- Smart gradient calculations that improve efficiency - Tim Brick has made substantial progress on and will continue to finish it in upcoming weeks.
- Creating a versions of solnp in C so that OpenMx can be distributed as a CRAN package - Ross Gore is rewriting the Rsolnp package (written in R) in C.
- Multilevel modeling - Michael Spiegel is exploring the viability of an interface specced out by the group several months ago.
- Improved Methods to Handle Data in OpenMx in a variety of contexts
- Multilevel OpenMx Data
- Likelihood data that goes across different machines
- Heterogeneous Data
- Swift R Integration
- Relational Database methods (sql-like) to query data
- Bayesian Objective Function - no immediate action, there maybe some progress on this starting in two or three weeks.
