Nevertheless, some data sets only show the linear behaviour for values larger than a given bound. When this happens, one needs to use a more flexible probability distribution. In this work the Zipf distribution is generalized by means of the MarshallOlkin transformation. The resulting distribution, denoted as MarshallOlkin Extended Zipf distribution (MOEZipf), is a twoparameter distribution that exhibits more flexibility in modelling the probability of the first positive integer values, while keeping the linear behaviour in the tail. Here the main properties of the MOEZipf family of distributions are presented, and several real data sets are analyzed. The results obtained prove the usefulness of the generalized model. 
Dimensional Analysis and its Applications in Statistics

and physical sciences for analytically reducing the number of
experimental variables prior to the experimentation.
The principle use of dimensional analysis is to reduce from a study
of the dimensions of the variables on the form of
any possible relationship between those variables.
The method is of great generality.
In this talk, an overview/introduction of DA will be first given.
A basic guideline for applying DA will be proposed,
using examples for illustration.
Some initial ideas on using DA for Data Analysis and Design of
Experiment will be discussed.

Design and Sensitivity Analysis for Functional Inputs in Computer Experiments

Our specific aim is to not only get the sensitivity of the function as a whole, but to obtain a function of sensitivities that provides information on the influence of the different points (e.g. in time or space). We handle the huge dimension of this problem by exploring whole intervals of the functional domain at once. The input variables are, therefore, designed as piecewise constant functions, similar to Bsplines of order 1. Then, we sequentially refine the interval size for interesting spaces of the functional domain. This results in a piecewise constant sensitivity for each functional input pointing out important and unimportant domain parts. Finally, the talk presents a current application in sheet metal forming with friction and blank holder force as functional inputs.

The purpose of this study is decreasing the waiting time in hospitals and pharmacies, using resources more efficient and reducing the circulation time for patients. In this study, the number of people who visits the hospitals and pharmacies on duty in a month and the number of hospitals and pharmacies on duty are counted. According to these data current system simulation was modeled in ARENA. Alternative scenarios are developed for working schedules and locations of hospitals and pharmacies on duty in Isparta Downtown and it is compared with current state. The answers of the farther questions is tried to determine from the results that how many doctors and health staff is needed in which hospital, the locations of the pharmacies and which days which pharmacies should stay open.
