Abstract

The use of precise stochastic parameter models, such as the normal, log-normal, exponential, poisson and gamma models, is nowadays deeply entrenched in statistical practice. The cause of this trend is their ability to approximately represent a series of data that can be easily described and interpreted. Nevertheless, it is well known that the real world doesn't behave as these models describe it. Recently, a statistical technique, employing parametrical models, appeared. This method tests part of the assumed model that is, although it employs parametrical models the procedure, it builds, doesn't fundamentally depend on the included hypothesis.
