The goal of this paper is to investigate the relation between object-oriented design choices and defects in software systems, with focus on a real-time telecommunication domain. The design choices are measured using the widely accepted metrics suite proposed by Chidamber and Kemerer for object oriented languages [S.R. Chidamber, C.F. Kemerer, A metrics suite for object oriented design, IEEE Tra...

Lately, bivariate zero-inflated (BZI) regression models have been used in many instances in the medical sciences to model excess zeros. Examples include the BZI Poisson (BZIP), BZI negative binomial (BZINB) models, etc. Such formulations vary in the basic modeling aspect and use the EM algorithm (Dempster, Laird and Rubin, 1977) for parameter estimation. A different modeling formulation in the ...

Citation is considered as the most popular quality assessment metric for scientific papers, and it thus important to determine what factors promote citation count of a paper in comparison others same field. The main aim this study model counts research published SCI or SCI-Expanded journals Statistics field with growing number works Turkey. It well known that right-skewed nature makes classical...

In this paper, we construct a new Lagrangian discrete distribution, named the zero truncated Poisson distribution (LZTPD). It can be presented as generalization of Poissson (ZTPD) and an alternative to intervened (IPD), which was elaborated for modelling both over-dispersed under-dispersed count datasets. The mathematical aspects LZTPD are thoroughly investigated, its connection other distribut...

Zero-inflated data indicates that the data set contains an excessive number of zeros. The word zero-inflation is used to emphasize that the probability mass at the point zero exceeds than the one allowed under a standard parametric family of discrete distributions. Gupta et al. [1], Murat & Szynal [2], Patil & Shirke [3] have contributed to estimation and testing of the parameters involved in Z...

Text data modeling has been usually considered with Bernoulli or multinomial event models. Poisson distribution is considered inefficient for text information retrieval. In this work, we propose to incorporate the Zero Inflated Poisson model in the Generative Topographic Mapping algorithm. The modified algorithm is presented as a text document cluster extraction and visualization tool. Experime...
