Conditional estimation in two‐stage adaptive designs [PDF]

open access: greenBiometrics, 2017
We consider conditional estimation in two-stage sample size adjustable designs and the following bias. More specifically, we consider a design which permits raising the sample size when interim results look rather promising, and, which keeps the ...

Two-stage benchmarking as applied to small area estimation [PDF]

open access: greenTEST, 2013
There has been recent growth in small area estimation due to the need for more precise estimation of small geographic areas, which has led to groups such as the U.S.

TWO-STAGE HUBER ESTIMATION [PDF]

open access: yesJournal of Statistical Planning and Inference, 2007
In this paper we study how the Huber estimator can be adapted to the presence of endogeneity in a two stage equations setting similar to that of 2SLS. We propose an estimation procedure that is at the same time relatively (i) simple, (ii) robust and (iii)

On Two-Stage Non-Parametric Estimation [PDF]

open access: goldThe Annals of Mathematical Statistics, 1964
Abstract : A two-sample, two-stage non-parametric estimation problem is studied. The parameter phi phi(F, G) under consideration is estimable (i.e., there exists an unbiased estimator which is a function of independent observations from two populations with cumulative distribution functions F(X) and G(Y). (Hence, it is called a two-sample problem.) The

A two-stage rank test using density estimation [PDF]

open access: yesAnnals of the Institute of Statistical Mathematics, 1995
For the one-sample problem, a two-stage rank test is derived which realizes a required power against a given local alternative, for all sufficiently smooth underlying distributions. This is achieved using asymptotic expansions resulting in a precision of

Two-stage Channel Frequency Response Estimation in OFDM Systems [PDF]

open access: yes, 2020
This paper proposes two-stage channel frequency response estimation algorithm in communication systems with OFDM technology. Algorithm is based on Kalman filter. Pilots from current and previous OFDM symbols are used for channel estimation.

Off-Grid DoA Estimation via Two-Stage Cascaded Neural Network

open access: yesEnergies, 2021
This paper introduces an off-grid DoA estimation via two-stage cascaded network which can resolve a mismatch between true direction-of-arrival (DoA) and discrete angular grid.

Two-Stage Fast DOA Estimation Based on Directional Antennas in Conformal Uniform Circular Array

open access: yesSensors, 2021
In conformal array radar, due to the directivity of antennas, the responses of the echo signals between different antennas are distinct, and some antennas cannot even receive the target echo signal.

Threshold Value Estimation Using Adaptive Two-Stage Plans in R

open access: yesJournal of Statistical Software, 2015
This paper introduces the R package twostageTE for estimation of an inverse regression function at a given point when one can sample an explanatory covariate at different values and measure the corresponding responses.
