A General Method of Density Estimation for Negatively Associated Random Variables
Let be a stationary sequence of negatively associated
random variables having a common marginal density function f(x). Let
{X n , n ≥ 1}
(x, y), n ψ n =
1, 2, L be a sequence of Borel-measurable ...
Almost sure convergence of two-dimensional distribution function under negative association
Let {Xi, i 1} be a sequence of negatively associated and strictly stationary
random variables having marginal distribution function F. Suppose #l(r, s) =
P(X1 r,Xl+1 s)−F(r)F(s). We prove an exponential ...
Kaplan-Meier Estimator for Associated Random Variables Under Left Truncation and Right Censoring
It is assumed that in long term studies the lifetimes are positively (negatively) associated random
variables. Under some regular conditions, the strong convergence rates of Kaplan-Meier estimator
of marginal ...
Almost sure convergence of kernel bivariate distribution function estimator under negative association
Let {Xn, n ≥ 1} be a strictly stationary sequence of negatively associated random variables, with
common distribution function F. In this paper, we consider the estimation of the two-dimensional
distribution ...
Exponential rates for negatively associated random variables based on kernel density function
Under mild conditions on the covariance structure of the sample, we estimate density function of negatively associated random variables based on kernel estimator and prove exponential rates for this estimator with a uniform ...
مقایسه قابلیت اعتماد سیستم های موازی و 2 از n با مؤلفه آماده به کار تحت وابستگی
Parallel systems are magnificently used in engineering due to availing a longer and more reliable lifetime of systems. Recently, employing standby units in systems has increased the reliability and finally benefits of the ...
Almost sure convergence of kernel bivariate distribution function estimator under negative association
Let {Xn, n ≥ 1} be a strictly stationary sequence of negatively associated random variables, with
common distribution function F. In this paper, we consider the estimation of the two-dimensional
distribution ...
On almost sure convergence for weighted sums of pairwise negatively quadrant dependent random variables
Let {Xn, n ≥ 1} be a sequence of pairwise negatively quadrant dependent
(NQD) random variables. In this study, we prove almost sure limit theorems for
weighted sums of the random variables. From these results, ...
Dipyridamole stress and rest gated 99mTc-sestamibi myocardial perfusion SPECT: left ventricular function indices and myocardial perfusion findings
Introduction: We investigated the difference in left ventricular ejection fraction (LVEF) and end-systolic volume(ESV) measured by gated myocardial perfusion SPECT (GSPECT) in the post-dipyridamole stress and rest periods, ...
