Description: An increasing need exists for the actuary to provide ranges and frequency distributions of possible values instead of providing only mean values. This discussion will cover: projections of asset experience under various economic scenarios, a practical application of profit analysis using scenarios and a deterministic model, exploring possible values by means of stochastic modeling, and a description of the new life contingencies textbook's stochastic approach and application to some practical population and census problems. From Record of the Society of Actuaries 1981, Volume 7, No. 4.
