The Statistical Analysis of General Processing Tree Models with the EM Algorithm.

Peer reviewed

Hu, Xiangen; Batchelder, William H. – Psychometrika, 1994

The statistical analysis of processing tree models is advanced by showing how the parameters of estimation and hypothesis testing, based on the likelihood functions, can be accomplished by adapting the expectation-maximization (EM) algorithm. The adaptation makes it easy to program a personal computer to accomplish the stages of statistical…

Microcomputers and Biology Teaching--An Overview and Some Ideas for Future Development.

Peer reviewed

Tallon, Bill; And Others – School Science Review, 1983

Discusses use of microcomputers for structuring, communicating, and disseminating information under the categories of instructional use (computer-assisted instruction), emancipation (number crunching), revelatory (discovery/simulation), and conjectural (hypothesis testing). Also discusses use of PROLOG language for modeling ecosystems and testing…
