AppleTree Version History

Version History

For identifiability checks, all free parameters are reported in every run together with G-Square values.
Redesign of the tree graph generation algorithm. The former algorithm was not able to find a tree corresponding to the equations in all cases.
Redesign of the parameter list for easier editing
Minor cosmetic changes

The parameter estimation process is significantly faster than in previous versions.
Some commands are moved from the AppleTree window to the menu bar.
Extended Drag&Drop support: Equation files can be dropped on the Model field. Data files can be dropped on the Data field. Tree graphs can be dragged from their window to any other program supporting Drag&Drop for PICTs.
Trees and categories can now have names instead of numbers.
The order of parameters in the branch equations must be the same as their order in the tree.
Minor cosmetic changes

Improved error detection in model files
When double clicked in the Finder, AppleTree text files are automatically entered as model files if the extension is ".eqn" and as data files if the extension is ".mdt".
Upon opening a text file in AppleTree, the program now checks, whether there is already a window for this file.
Minor cosmetic corrections

Fixes a bug introduced in version 1.1.0: The estimation process did not work correctly if lambda was set to 1.

Expected data sets are output to a window rather than written to a file.
Expected data sets can be generated without any empirical data file specified.
Unchecking Cohen's "w" in the Power Analysis field no more forces the lambda parameter to 1.
Fixed an error in the computation of the Power Divergence Statistic for lambda = -1
Uses Apple's Navigation Services for file dialogs if present
Various graphical interface problems fixed

Support for proportional scroll bars (MacOS 8.5 or later)
Arrow buttons for adjusting the step width while the estimation process is running
Better Appearance Manager support
