Objective Tuberculosis remains a major global health challenge, with delayed diagnosis contributing to increased transmission and disease burden. While microbiological tests are the gold standard for confirming active tuberculosis, many cases lack mi

This research paper stands for the estimation of the precision matrix of the normal matrix with monotone missing data. We explicitly provide maximum and expectation a posteriori estimators. For this purpose, we basically use an extension of the Wisha

This research paper stands for an extension to the multivariate t?distribution introduced in 1954 by Cornish, Dunnett and Sobel, namely the multiparameter t?distribution. This distribution is expressed in two different ways. The first way invests the

This paper deals with the statistical studies of the normal tempered stable model defined by Barndorff-Nielsen and Shephard. It represents the natural extension of the normal inverse Gaussi...

This paper presents new approaches to forecast the plant growth based on statistical methods: autoregressive and Markov chain models, using a time series of the normalized different vegetation index. Here, a monthly normalized different vegetation in

Many database search methods have been developed for peptide identification throughout a large peptide data set. Most of these approaches attempt to build a decision function that allows the identification of an experimental spectrum. This function i

This paper deals with the study of the maximum likelihood estimator of the scale parameter for the Riesz distribution. This distribution represents a natural generalization of the Wishart distribution. We give an explicit formula of this estimator an

This paper deals with a characterization of a multivariate stable process using an independence property with a positive random variable. Moreover, we establish a characterization of a multivariate Levy process based on the notion of cut in a natural

This paper deals with the characterization of a class of infinitely divisible mixture distributions when the mixing parameter is the power of convolution. In framework of natural exponential families, we give the expression of its variance function.
