摘要:In this paper, inspired by the estimator of the cumulated specific incidence proposed by Marubini and Vasecchi [23], we obtain the Kaplan-Meier estimator of the survival function of all causes of death combined by summing the estimator of fj(t) (j 2 {1, . . . ,m}) obtained by plu...

摘要:The community detection is one of the main problems in social network analysis. Many methods are proposed to recover the community labels of nodes by assuming the number of communities is known. There has been an increasing interest to explore the communities number. We propose a...

摘要:To better supervise the risk of financial investment market, the Conditional Value At Risk (CVaR) investment portfolio optimization model of under single period investment is discussed and its expansion form is explained. The empirical simulation of Mean - CVaR model is carried o...

摘要:The semi-parametric estimation under the proportional hazards (PH) model with a linearly time-dependent covariates and with interval-censored data has not been investigated before. The partial likelihood approach does not work and one has to use the generalized likelihood functio...

摘要:Based on the presentation of dynamic and nonlinear data forecast, we discuss the difference in two approaches, Multi-layer feed-forward artificial neural networks and ordinary least squares regression for students’ enrolment forecast in FUTO, Nigeria. A simple procedure to i...

摘要:The idea of “Mixed Allocation” in stratified sampling was introduced by [4]. The concept was further developed by several authors in different manner. In the present paper the authors worked out the “Compromise Mixed Allocation” for multivariate stratified sampling for ...

摘要:Yu and Diao [1] studied the estimation problem under the Cox model with linearly time-dependent covariates and with interval-censored (IC) data under the distribution-free set-up. They proposed a modified semi-parametric MLE (MSMLE) and the simulation results suggest that the MSM...

摘要:The purpose of survival analysis is to model the underlying distribution of the failure time variable and to assess the dependence of the failure time variable on independent variables. In this paper, we explored PHREG procedure for different models using Bayesian approach. ...

摘要:In this paper we propose a new generalized counting process with extension of exponential inter-arrival time distribution. This new model is a generalization of the exponential distribution. The computational intractability is overcome by deriving the extension of exponential cou...

摘要:The purpose of this research is to propose a new method for detecting change points with an epidemic alternative (in the form of a step function). There are several parametric approaches and nonparametric approaches in the literature that can be used for detecting change-poi...
