Two Stage and Related Estimators and Their Applications [PDF]

The Review of Economic Studies, 1986
This paper aims to provide a unified treatment of the properties of two stage estimators. General conditions are set forth for consistency, efficiency and correct inferences. Applications of the general theorems are made to models with expectations and diagnostic tests. The general approach frequently enables much simpler derivation of existing results,

Individual participant data meta-analysis for a binary outcome: one-stage or two-stage? [PDF]

PLoS ONE, 2013
A fundamental aspect of epidemiological studies concerns the estimation of factor-outcome associations to identify risk factors, prognostic factors and potential causal factors.

Two-Stage Estimation for Ultrahigh Dimensional Sparse Quadratic Discriminant Analysis

Journal of Mathematics
The conventional Quadratic Discriminant Analysis (QDA) encounters a significant hurdle due to parameter scaling complexities on the order of Op2, rendering it impractical for the analysis of high or ultrahigh dimensional data. This arises especially when

MRIE: Enhanced Rainfall Intensity Estimation With Two-Stage Multimodal Deep Learning

IEEE Access
Accurate rainfall intensity estimation is crucial for environmental monitoring and urban planning. However, the reliability of existing methods in practical applications is relatively low due to certain deficiencies in data processing and noise ...

Inference for Two-Stage Extremum Estimators

SSRN Electronic Journal
We present a simulation-based inference approach for two-stage estimators, focusing on extremum estimators in the second stage. We accommodate a broad range of first-stage estimators, including extremum estimators, high-dimensional estimators, and other types of estimators such as Bayesian estimators.

Estimating Reference Ranges from Stratified Two-stage Samples

Journal of the Royal Statistical Society Series A: Statistics in Society, 2001
Summary We present methodology for estimating age-specific reference ranges by using data from two-stage samples. On the basis of the information obtained in the first stage, the initial sample is stratified and random subsamples are drawn from each stratum, where the selection probabilities in this second-stage sampling may be different

Two-Stage Kalman Filter for Fault Tolerant Estimation of Wind Speed and UAV Flight Parameters

Measurement Science Review, 2020
In this study, an estimation algorithm based on a two-stage Kalman filter (TSKF) was developed for wind speed and Unmanned Aerial Vehicle (UAV) motion parameters. In the first stage, the wind speed estimation algorithm is used with the help of the Global

A Two-Stage Algorithm to Estimate the Fundamental Frequency of Asynchronously Sampled Signals in Power Systems

Energies, 2015
A two-stage algorithm is proposed for the estimation of the fundamental frequency of asynchronously sampled signals in power systems. In the first stage, time-domain interpolation reconstructs the power system signal at a new sampling time and the ...
