AppleTree

A Multinomial Processing Tree Modeling Program for Macintosh Computers

Purpose

AppleTree is an application for fitting multinomial binary tree models 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. AppleTree is freeware. It runs natively on both 680x0 and PowerPC Macs.

Requirements

MacOS 7.5 or later. MacOS 8.5 or later recommended.
Motorola 68020 or better (no FPU required) or any PowerPC. PowerPC recommended.

Availability

You can get AppleTree by FTP either from ftp://cogpsy.uni-trier.de/pub/AppleTree/ or from your local info-mac mirror (in the "sci" directory).
The current version is 1.3.3.
