this paper is concerned with the problem of finding the minimax estimators of the scale parameter ? in a family of transformed chi-square distributions, under asymmetric squared log error (sle) and modified linear exponential (mlinex) loss functions, using the lehmann theorem [2]. also we show that the results of podder et al. [4] for pareto distribution are a special case of our results for th...

Assessing similarity between features is a key step in object recognition and scene categorization tasks. We argue that knowledge on the distribution of distances generated by similarity functions is crucial in deciding whether features are similar or not. Intuitively one would expect that similarities between features could arise from any distribution. In this paper, we will derive the contrar...

We present a model for the distribution of family names that explains the power-law decay of the probability distribution for the number of people with a given family name. The model includes a description of the process of generation or importation of new names, and a description of the growth of the number of individuals with a name, and corresponds for a long-enduring culture to a Galton–Wat...

The traditional approach with microarray data has been to apply transformations that approximately normalize them, with the drawback of losing the original scale. The alternative stand point taken here is to search for models that fit the data, characterized by the presence of negative values, preserving their scale; one advantage of this strategy is that it facilitates a direct interpretation o...

in this paper, we obtain  bayesian prediction intervals as well as bayes predictive estimatorsunder square error loss for generalized order statistics when the distribution of the underlying population belongs to a family which includes several important distributions.

This article describes the results of research to improve estimates of the distribution of family income. In this research, a microdata file was constructed for 1972 using several data sources. The data obtained from these sources were combined and adjusted to produce more precise estimates. Current Population Survey estimates were then evaluated using these improved estimates. Using the improv...

Process in software engineering is a growing concern for many software development organizations. The need for well-educated software engineers is bringing new software engineering programs to universities. In many programs, software process education adds up to a few hours of lectures in an introductory software engineering course. This paper presents the structure and the content for a full, ...

In hospital cardiac arrest are rare events in paediatrics. Most children receive appropriate care without experiencing undetected severe clinical deterioration during hospital admission. Outcomes of paediatric cardiac arrests are however generally poor, with high mortality rates and neurological damage at survival. A review of child mortality in the UK showed that a high proportion of unexpecte...

OBJECTIVES The aim of this study was to investigate the existence of correlation between the TNM clinical classification, anatomical location and prognosis of oral squamous cell carcinoma. STUDY DESIGN A total of 130 oral squamous cell carcinomas were selected from the files of the Dr. Luiz Antonio Hospital (Natal, Rio Grande do Norte, Brazil). Data concerning TNM clinical classification, ana...
