Auxiliary variables and recursive procedures [PDF]

, 1997
Much research in axiomatic semantics suffers from a lack of formality. In particular, most proposed verification calculi for imperative programs dealing with recursive procedures are known to be unsound or incomplete. Focussing on total correctness, we present a new consequence rule which yields a sound and complete Hoare-style calculus in the presence

Some Efficient Methods to Remove Bias in Ratio and Product Types Estimators in Ranked Set Sampling

International Journal of Bio-Resource and Stress Management, 2022
Ranked set sampling is one method to potentially increase precision and reduce costs by using quantitative or qualitative information to obtain a more representative sample.

A note on transformations on auxiliary variable in survey sampling [PDF]

Model Assisted Statistics and Applications, 2011
In this note, we address the doubts of Singh [12] and Gupta and Shabbir [1] on the transformations of auxiliary variables by adding unit free constants. The original contribution by Sisodia and Dwivedi [15] is correct.

Referral Patterns and Diagnostic Timeliness in Pediatric Cancer: A Hospital‐Based Study in Indonesia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Timely diagnosis and treatment are critical for improving survival among children with cancer. In low‐ and middle‐income countries (LMICs), delays are common and may be influenced by fragmented referral pathways and diagnostic limitations.

A robust population mean estimation method in stratified sampling using auxiliary attributes under real and simulated populations

Advanced Modeling and Simulation in Engineering Sciences
This study proposes a novel improved ratio-type estimator for efficient estimation of the population mean in stratified sampling by integrating auxiliary attribute information through a unified nonlinear framework. Unlike conventional ratio, product, and

Imputation of missing data for domain mean estimation using simple random sampling

Kuwait Journal of Science
The estimate of domain mean is a significant issue in sample surveys. However, if the data is missing, it becomes very necessary. In the case of missing data, this paper proposes some direct and synthetic domain mean estimators using simple random ...

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Estimation of population mean using ranked set sampling in the presence of measurement errors

Kuwait Journal of Science
Ranked set sampling is widely acknowledged for its superior efficiency compared with simple random sampling. Only a small amount of work has been conducted using ranked set sampling when measurement errors are present.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

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 ...
