Classical methods of estimation on constant stress accelerated life tests under exponentiated Lindley distribution [0.03%]
基于Lindley分布的恒定应力加速寿命试验的经典估计方法
Sanku Dey,Mazen Nassar

Accelerated life testing is adopted in several fields to obtain adequate failure time data of test units in a much shorter time than testing at normal operating conditions. The lifetime of a product at constant level of stress is assumed to...
Sparse graphical models via calibrated concave convex procedure with application to fMRI data [0.03%]
基于校准的凹凸算法的稀疏图模型及其在fMRI数据中的应用
Sungtaek Son,Cheolwoo Park,Yongho Jeon
Sungtaek Son
This paper proposes a calibrated concave convex procedure (calibrated CCCP) for high-dimensional graphical model selection. The calibrated CCCP approach for the smoothly clipped absolute deviation (SCAD) penalty is known to be path-consiste...
The unit-Weibull distribution as an alternative to the Kumaraswamy distribution for the modeling of quantiles conditional on covariates [0.03%]
单位威布尔分布作为 Kumaraswamy 分布的替代方法用于条件协变量下的分位数建模
J Mazucheli,A F B Menezes,L B Fernandes et al.
J Mazucheli et al.
The Beta distribution is the standard model for quantifying the influence of covariates on the mean of a response variable on the unit interval. However, this well-known distribution is no longer useful when we are interested in quantifying...
A Cholesky-based estimation for large-dimensional covariance matrices [0.03%]
基于Cholesky分解的大维协方差矩阵估计方法

Xiaoning Kang
This paper develops a new method to estimate a large-dimensional covariance matrix when the variables have no natural ordering among themselves. The modified Cholesky decomposition technique is used to provide a set of estimates of the cova...
A bivariate inverse Weibull distribution and its application in complementary risks model [0.03%]
互补风险模型下的双变量逆韦伯分布及其应用
Shuvashree Mondal,Debasis Kundu
Shuvashree Mondal
In reliability and survival analysis the inverse Weibull distribution has been used quite extensively as a heavy tailed distribution with a non-monotone hazard function. Recently a bivariate inverse Weibull (BIW) distribution has been intro...
Jumps beyond the realms of cricket: India's performance in One Day Internationals and stock market movements [0.03%]
超越板球的界限：印度_ODI_表现与股市波动的关系
Konstantinos Gkillas,Rangan Gupta,Chi Keung Marco Lau et al.
Konstantinos Gkillas et al.
We examine the impact of the Indian cricket team's performance in one-day international cricket matches on return, realized volatility and jumps of the Indian stock market, based on intraday data covering the period of 30th October, 2006 to...
Forecasting interest rate volatility of the United Kingdom: evidence from over 150 years of data [0.03%]
基于150余年的数据看英国利率波动性预测
Hossein Hassani,Mohammad Reza Yeganegi,Juncal Cuñado et al.
Hossein Hassani et al.
This study examines the very short, short, medium and long-term forecasting ability of different univariate GARCH models of United Kingdom (UK)'s interest rate volatility, using a long span monthly data from May 1836 to June 2018. The main ...
Monitoring of zero-inflated binomial processes with a DEWMA control chart [0.03%]
基于DEWMA控制图的过度离散二项分布的状态监测方法研究

Vasileios Alevizakos
Control charts are widely used for monitoring quality characteristics of high-yield processes. In such processes where a large number of zero observations exists in count data, the zero-inflated binomial (ZIB) models are more appropriate th...
A combined mixed- s-skip sampling strategy to reduce the effect of autocorrelation on the X̄ scheme with and without measurement errors [0.03%]
一种混合s-skip抽样策略的结合体以减少自相关对X ̄方案的影响（含或不含测量误差）

Sandile Charles Shongwe
In order to reduce the effect of autocorrelation on the X ¯ monitoring scheme, a new sampling strategy is proposed to form rational subgroup samples of size n. It requires sampling to be done such that: (i) observations from two con...
Double and group acceptance sampling plan for truncated life test based on inverse log-logistic distribution [0.03%]
基于截尾寿命试验的逆对数logistic分布的双层和分组抽样检验计划
Harsh Tripathi,Sanku Dey,Mahendra Saha
Harsh Tripathi
This paper introduces a double and group acceptance sampling plans based on time truncated lifetimes when the lifetime of an item follows the inverse log-logistic (ILL) distribution with known shape parameter. The operating characteristic f...
