Abstract
In this paper we describe a microcomputer system developed by the Editors for illustration of various concepts related to regression analysis. Particular attention is paid to the diagnostics for analysing influential observations and outliers. Naturally graphical methods play a central role in this illustration. The system is mainly planned for a student taking a course in regression analysis or a person who is applying regression analysis and wants to know the meaning of diagnostics in practice. The programming language is the APL and thus the user familiar with the APL can easily extend the system by his own functions. The system is implemented on Apple Macintosh personal microcomputer and it is a part of a larger system, called KONSTA 88, which is planned for illustrating statistical concepts.
