Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Maintenance hemodialysis (MHD) patients frequently suffer from frailty, characterized by reduced physical function and poor prognosis. Myokines, such as myonectin, secreted by muscle, are emerging regulators of systemic health. This study investigated the relationship between serum myonectin, adipokines (adiponectin, omentin), and ...

Point estimates for probability moments [PDF]
Proceedings of the National Academy of Sciences, 1975 Given a well-behaved real function Y of a real random variable X and the first two or three moments of X , expressions are derived for the moments of Y as linear combinations of powers of the point estimates y(x

Estimating the Conditional Tail Expectation in the Case of Heavy-Tailed Losses
Journal of Probability and Statistics, 2010 The conditional tail expectation (CTE) is an important actuarial risk measure and a useful tool in financial risk assessment. Under the classical assumption that the second moment of the loss variable is finite, the asymptotic normality of the ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

A fast robust numerical continuation solver to a two‐dimensional spectral estimation problem
IET Control Theory & Applications, 2022 This paper presents a fast algorithm to solve a spectral estimation problem for two‐dimensional random fields. The latter is formulated as a convex optimization problem with the Itakura‐Saito pseudodistance as the objective function subject to the ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Equivariant adjusted least squares estimator in two-line fitting model
Modern Stochastics: Theory and Applications, 2016 We consider the two-line fitting problem. True points lie on two straight lines and are observed with Gaussian perturbations. For each observed point, it is not known on which line the corresponding true point lies.

k-Class Estimators of Coefficients in Seemingly Unrelated Regression Equations [PDF]
The Egyptian Statistical Journal, 1983 This paper develops a new family of biased estimators, namely, the k-class, for the parameters of the seemingly unrelated regression equations. Expressions for the exact and approximate bias, moment matrix, and the risk function of the k-class estimator ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Peritoneal dialysis (PD) is an established home‐based kidney replacement therapy (KRT), but its uptake remains low in Japan. We evaluated whether individualized education in a dedicated outpatient clinic was associated with the initiation of PD.

Parameter Estimation of Weibull Distribution Based on Second-Kind Statistics
Journal of Communications Software and Systems, 2010 The log-cumulant estimator is proposed to estimate the parameters of Weibull distribution based on second-kind statistics. With the explicit closed form expressions, the log-cumulant estimator is computationally efficient.
