On Two-Stage Non-Parametric Estimation [PDF]

open access: yesThe Annals of Mathematical Statistics, 1963
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

Characterization of the asymptotic distribution of semiparametric M-estimators [PDF]

open access: yes, 2010
This paper develops a concrete formula for the asymptotic distribution of two-step, possibly non-smooth semiparametric M-estimators under general misspecification.

Two-stage robust optical flow estimation [PDF]

open access: yesProceedings IEEE Conference on Computer Vision and Pattern Recognition. CVPR 2000 (Cat. No.PR00662), 2002
We formulate optical flow estimation as a two-stage regression problem. Based on characteristics of these two regression models and conclusions on modern regression methods, we choose a least trimmed squares followed by a weighted least squares estimator to solve the optical flow constraint (OFC); and at places where this one-stage robust method fails ...

Two-stage re-estimation adaptive design: a simulation study

open access: yesEpidemiology, Biostatistics and Public Health, 2013
Background: adaptive clinical trial design has been proposed as a promising new approach to improve the drug discovery process. Among the many options available, adaptive sample size re-estimation is of great interest mainly because of its ability to ...

Two-Stage Channel Estimation for Semi-Passive RIS-Assisted Millimeter Wave Systems

open access: yesSensors, 2022
In a reconfigurable intelligent surface (RIS) assisted millimeter Wave (mmWave) communication system, the channel coefficient increases exponentially with the number of RIS elements which results in expensive pilot overhead.

Beyond Support in Two-Stage Variable Selection [PDF]

open access: yes, 2015
Numerous variable selection methods rely on a two-stage procedure, where a sparsity-inducing penalty is used in the first stage to predict the support, which is then conveyed to the second stage for estimation or inference purposes.

Estimation of Tropical Cyclone Intensity via Deep Learning Techniques from Satellite Cloud Images

open access: yesRemote Sensing, 2023
Estimating the intensity of tropical cyclones (TCs) is usually involved as a critical step in studies on TC disaster warnings and prediction. Satellite cloud images (SCIs) are one of the most effective and preferable data sources for TC research. Despite

Two-Stage Maximum Score Estimator

open access: yes, 2020
This paper considers the asymptotic theory of a semiparametric M-estimator that is generally applicable to models that satisfy a monotonicity condition in one or several parametric indexes. We call the estimator two-stage maximum score (TSMS) estimator since our estimator involves a first-stage nonparametric regression when applied to the binary choice
