This paper extends the work of Pimentel et al. (2015), presenting an estimator Kendall’s τ for bivariate zero-inflated count data. We provide achievable bounds our proposed and suggest how to estimate them, thereby making useful in practice.

Due to the expansion of internet, we encounter various types big data such as web documents or sensing data. Compared traditional small experimental samples, provide more chances find hidden and novel patterns with analysis using statistics machine learning algorithms. However, use increases, problems also occur. One them is a zero-inflated problem in structured preprocessed from Most count val...

Rapid technological advancement and implementation of automation computerization in today's manufacturing set up resulted many high quality processes, where defects are rarely observed. There processes two or more types may be generated from different equipment/process problems. The zeroinflated data containing commonly modeled by bivariate zero-inflated (BZI) Poisson distribution. Pal Gauri (2...

There has been a considerable amount of work devoted by transportation safety analysts to the development and application of new and innovative models for analyzing crash data. One important characteristic about crash data that has been documented in the literature is related to datasets that contained a large amount of zeros and a long or heavy tail (which creates highly dispersed data). For s...

Applications in which data take nonnegative values but have a substantial proportion of values at zero occur in many disciplines. The modeling of such “clumped-at-zero” or “zero-inflated” data is challenging. We survey models that have been proposed. We consider cases in which the response for the non-zero observations is continuous and in which it is discrete. For the continuous and then the d...

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...
