DINDE: Towards more sophisticated software environments for statistics .* R.W. Oldford and S.C. Peters Massachusetts Institute of Technology Abstract A prototype statistical system we call DINDE is described. DINDE is aimed at the professional statistician and provides a statistical analysis environment that is more sophisticated than the current generation of systems. In particular, it allows the analyst to keep careful track of the entire analysis as it progresses. General design philosophy and some issues of implementation are described and an example session is presented for illustration. * The authors gratefully acknowledge D.A. Belsley, E. Kuh, A.
