The OpenMx development team discussed the following on January 25:
- Andreas Brandmaier, Tim Brick, and Timo von Oertzen presented a demo version of an mxPlot command that calls Onyx to draw a diagram corresponding to an MxModel object. I believe the demo was largely made by Andreas. Several aspects of the user interface were discussed at length.
- Tim Brick presented a draft/proposal for multilevel modeling. Most of the math is worked out, and we're discussing the diagrams. We agree that there should be blocks with the model for each level within a block, but we are debating how connections should be made across blocks/levels.
- Joshua Pritikin is working on some of the multilevel coding with Timo von Oertzen and should have something finished for the hierarchical case in about three months.
