By “z” is meant the appropriate value of the standard normal variate. Percentage and percentile calculations are exact for a population and are approximate for a sample from a population. Confidence l
Our goal is to provide a valid point of reference for the theoretical study and the practical use of the Non-central Dirichlet distribution. An Achilles' heel of such model is the limited mathematical
A new family of distributions called type II exponentiated half logistic is introduced and studied. Four new special models are presented. Some mathematical properties of the new family are studied. E
