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.
Information about how the data was generated can help you decide whether the Poisson distribution fits. The Poisson distribution is based on four assumptions. We will use the term interval to refer to either a time interval or an area, depending on the context of the problem.
