Appletree

AppleTree is an application for statistical modeling. It allows to fit multinomial binary tree models of arbitrary size to frequency data using the "General Processing Tree" algorithm developed by Hu and Batchelder (1994). AppleTree can read model files and data files written for the MS-DOS "MBT" program developed by Xiangen Hu, University of Memphis, Tennessee. Multinomial models can be created with a built in graphical editor. Restrictions to the models can be added using a graphical interface. AppleTree fits model parameters to frequency data, it provides estimates for the free parameters together with confidence intervals, it provides power analyses for a given model, and it allows for checking the identifiability of a model. AppleTree is freeware. It runs natively on both 680x0 and PowerPC Macs. See for latest informations. Changes since version 1.2.1: * Graphical model editor * Power analysis * Generates expected data sets for a given model * MacOS 8.5 support (Appearance Manager, Navigation Services, proportional scrollbars, etc.)
