Comparison of randomized branch sampling with and without replacement at the first stage

open access: yesSilva Fennica, 2005
Randomized Branch Sampling (RBS) is a multistage sampling procedure using natural branching in order to select samples for the estimation of tree characteristics. Usually, sampling units are selected with unequal probabilities.

Warfarin maintenance dose prediction for Chinese after heart valve replacement by a feedforward neural network with equal stratified sampling

open access: yesScientific Reports, 2021
Patients requiring low-dose warfarin are more likely to suffer bleeding due to overdose. The goal of this work is to improve the feedforward neural network model's precision in predicting the low maintenance dose for Chinese in the aspect of training ...

Asymptotic genealogies for a class of generalized Wright–Fisher models

open access: yesModern Stochastics: Theory and Applications, 2021
A class of Cannings models is studied, with population size N having a mixed multinomial offspring distribution with random success probabilities ${W_{1}},\dots ,{W_{N}}$ induced by independent and identically distributed positive random variables ${X_{1}

Estimation of the current population total for a four-phase sampling design

open access: yesNonlinear Analysis, 2016
The combined ratio-type estimators of the finite population total and their variances in the case of sample rotation for two-phase and four-phase sampling schemes are constructed in the paper.

Demography of Total Joint Replacement Surgeries Performed in a Tertiary Care Hospital: A Cross-sectional Survey

open access: yesJournal of Nepal Medical Association, 2021
Introduction: Total joint replacement of hip and knee is considered as one of the most successful orthopedic surgeries in the twenty-first century because of the only solution to end-stage arthritis of these joints.

Consistent Sampling with Replacement

open access: yesCoRR, 2018
We describe a very simple method for `consistent sampling' that allows for sampling with replacement. The method extends previous approaches to consistent sampling, which assign a pseudorandom real number to each element, and sample those with the smallest associated numbers.

Algorithm Providing Ordered Integer Sequences for Sampling with Replacement Confidence Intervals

open access: yesAlgorithms
Sampling with replacement occurs when drawing without removing individuals from finite populations. It is a common distribution technique used in physics, biology, and medicine. It is used in state analysis of qubits, the physics of particle interactions,

Statistical Information: A Bayesian Perspective

open access: yesEntropy, 2012
We explore the meaning of information about quantities of interest. Our approach is divided in two scenarios: the analysis of observations and the planning of an experiment.

Are joint replacement registries associated with burden of revision changes? A real-world panel data regression analysis

open access: yesBMJ Open, 2023
Objectives The association of joint replacement registries with outcomes such as revision burden is uncertain. This study aimed to evaluate whether joint replacement registries are associated with the burden of revision changes while controlling for ...
