The CADA Monitor.
Christ, David E.
A system of computer-assisted data analysis (CADA) was developed at the University of Iowa to handle the mechanical, arithmetical and computational tasks associated with Bayesian statistical analysis. The original programs were subsequently expanded and a CADA monitor constructed to aid their use; a search was then undertaken to find a means of facilitating the monitor's application on diverse computer system. Since no entirely transportable language for all interactive systems existed, a strategy of interdialect translatability was pursued and BASIC was selected for use. A BASIC version of CADA was written and proved to be easily translatable. The monitor itself was designed so that no user programing skills were required and so that it was self-documenting and readily modifiable. In addition, the system was built so as not to leave its unsophisticated users hanging suspended when errors occurred, but to direct them ahead on the basis of available information. The two system features which most limited translatability across several systems were chaining and formatted print statements, but these were so desirable that they were retained. (LB)
