Abstract This article presents response of the author on comments made by scholars Jack Hayya, William Ferrara, and Erwin Saniga on the paper "Extending the Applicability of Probabilistic Management Planning and Control Models" that was published in the January 1974 issue of the periodical "The Accounting Review." One of the main points in the comment seems to revolve around the contention that recent advances in nonparametric statistical tests and the corresponding computer routines have made obsolete the use of Tchebycheff-type inequalities in probabilistic models. There are at least two possible reference points for defining the term obsolete. First, the term can be defined by referencing to the current level of technological feasibility, that is, what does one knows about the problems and techniques under consideration from a purely technological standpoint. Hayya and others are correct in stating that great advances have been made in the area of nonparametric statistics and the related computer routines. These advances have extended the technological feasibility of applying probabilistic planning and control models.
