The structure, design principles, and strategies of Mulreg

Mulreg is an interactive computing environment for data exploration, regression modeling, and the visualization and use of regression results. It is designed to allow both statisticians and nonstatisticians easy access to state-of-the-art tools for linear modeling. Design features of Mulreg are the object orientation of its internal data structures and of its user interface, its integration of graphics into every stage of the modeling process, the guidance provided by the menu layout, and the choice of statistical algorithms, which provide a consistent data analysis strategy to attack the great diversity of regression-type problems.
