Estimating abortion incidence using the network scale-up method

open access: yesDemographic Research, 2020
Background: A major challenge in abortion research is accurately measuring the incidence of induced abortion, particularly in restrictive settings. This study tests the network scale-up method (NSUM) to measure abortion incidence, which uses respondent ...

Estimating Functions in Indirect Inference

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 2004
SummaryThere are models for which the evaluation of the likelihood is infeasible in practice. For these models the Metropolis–Hastings acceptance probability cannot be easily computed. This is the case, for instance, when only departure times from a G/G/1 queue are observed and inference on the arrival and service distributions are required.

Decomposing heritability and genetic covariance by direct and indirect effect paths.

open access: yesPLoS Genetics, 2023
Estimation of heritability and genetic covariance is crucial for quantifying and understanding complex trait genetic architecture and is employed in almost all recent genome-wide association studies (GWAS).

Mean Ages at Parities: An Indirect Estimation [PDF]

open access: yesThe Pakistan Development Review, 1995
This paper is the outcome of a continuous concern that some of the basic demographic estimates provided by successive surveys in the country do not fulfil the expectation of use at their face value. In a previous paper, an indirect assessment of the birth rates from these surveys was made on the basis of internal consistency of ...

Adaptive Linear Quadratic Attitude Tracking Control of a Quadrotor UAV Based on IMU Sensor Data Fusion

open access: yesSensors, 2018
In this paper, an infinite-horizon adaptive linear quadratic tracking (ALQT) control scheme is designed for optimal attitude tracking of a quadrotor unmanned aerial vehicle (UAV). The proposed control scheme is experimentally validated in the presence of

Comparison of three indirect methods for verification and validation of reference intervals at eight medical laboratories: a European multicenter study

open access: yesJournal of Laboratory Medicine, 2023
Indirect methods for the indirect estimation of reference intervals are increasingly being used, especially for validation of reference intervals, as they can be applied to routine patient data.

Effects of 3D deformation and nonlinear stress–strain relationship on the Brazilian test for a transversely isotropic rock

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
To improve the accuracy of indirect tensile strength for a transversely isotropic rock in the Brazilian test, this study considered the three-dimensional (3D) deformation and the nonlinear stress–strain relationship.

An Indirect Method of Micromagnetic Structure Estimation in Microwires

open access: yesNanomaterials, 2021
The tunable magnetic properties of amorphous ferromagnetic glass-coated microwires make them suitable for a wide range of applications. Accurate knowledge of the micromagnetic structure is highly desirable since it affects almost all magnetic properties.
