Abstract Background Time-to-event data that is subject to interval censoring common in the practice of medical research and versatile statistical methods for estimating associations such settings have been limited. For right censored data, non-parametric pseudo-observations proposed as a basis regression modeling with possibility use different association measures. In this article, we propose m...

New upper bounds are developed for the $L_2$ distance between $\xi/\text{Var}[\xi]^{1/2}$ and linear quadratic functions of $z\sim N(0,I_n)$ random variables form $\xi=bz^\top f(z) - \text{div} f(z)$. The approximation yields a central limit theorem when squared norm $f(z)$ dominates Frobenius $\nabla f(z)$ in expectation. Applications this normal given asymptotic normality de-biased estimators...

To address the hesitancy, inconsistency and uncertainty of decision makers’ cognitions, linguistic interval hesitant fuzzy sets (LIHFSs) are efficient tools. This paper focuses on studying the application of LIHFSs. To do this, two correlation coefficients of LIHFSs are defined, which needn't consider the length of elements in LIHFSs or the arrangement of their possible interval values. To addr...

this paper proposes a method for ranking decision making units (dmus) using some of the multiple criteria decision making / multiple attribute decision making          (mcdm /madm) techniques, namely, interval analytic hierarchy process (iahp)          and the technique for order preference by similarity to an ideal solution (topsis).          since the efficiency score of unity is assigned to ...

The role of non-Archimedean  in the DEA models has been clarified, so that the associatedlinear programs can be infeasible (for the multiplier side) and unbounded (for theenvelopment side) with an unsuitable choice of  . This paper shows that the overallassurance interval for  in DEA models is unique by the concept of extreme directions. Also,it presents an assurance value for  using only s...
