Discounting principle. - Discounting principle: Discounting principle refers to a rule of Attribution which states that the perceived role of a cause will be discounted or reduced if other plausible causes are also present.
The Poisson Effect When a tensile stress is applied to a material, the material elongates in the direction of the applied stress, and contracts perpendicular to the direction of the applied stress. This relationship, called the Poisson effect, is a natural response to applied stress that occurs with all materials, but is particularly apparent with ductile materials. For example, when a metal bar is pulled in a tensile test, it stretches out and necks down on. the sides.
A variety of tests is available for testing whether a sample of observations comes from a Poisson. distribution. This article proposes an additional test based on Anscombeâs (1948) variance stabi-. lizing transformation. We examine the performance of this test and compare it with four other. tests in current use.
