Two-stage least squares and indirect least squares algorithms for simultaneous equations models
Journal of Computational and Applied Mathematics, 2012 This paper analyzes the solution of simultaneous equations models. Efficient algorithms for the two-stage least squares method using QR-decomposition are developed and studied. The reduction of the execution time when the structure of the matrices in each equation is exploited is analyzed theoretically and experimentally. An efficient algorithm for the

Estimation of Large-Scale Implicit Models Using 2-Stage Methods [PDF]
Modeling, Identification and Control, 1985 The problem of estimating large scale implicit (non-recursive) models by two- stage methods is considered. The first stage of the methods is used to construct or estimate an explicit form of the total model, by constructing a minimal stochastic ...

Determining welfare effects of technological improvement policy for sugar beet [PDF]
Majallah-i Chughundar-i Qand, 2012 As an industrial crop, sugar beet plays an important role in meeting domestic demand for sugar. Given the higher level of imported sugar inIran, the application of protectionist policies is an approach for supplying required sugar.

Two-Stage Least Squares with a Randomly Right-Censored Outcome [PDF]
SSRN Electronic Journal, 2021 This note develops a simple two-stage least squares (2SLS) procedure to estimate the causal effect of some endogenous regressors on a randomly right censored outcome in the linear model. The proposal replaces the usual ordinary least squares regressions of the standard 2SLS by weighted least squares regressions.

Two-stage least squares as minimum distance [PDF]
The Econometrics Journal, 2019 SummaryThe two-stage least-squares (2SLS) instrumental-variables (IV) estimator for the parameters in linear models with a single endogenous variable is shown to be identical to an optimal minimum-distance (MD) estimator based on the individual instrument-specific IV estimators.

Two-stage least squares model averaging for instrumental variable models with exogenous variables
Statistical Theory and Related FieldsInstrumental variable (IV) methods are widely used to address unmeasured confoundings in structural equation models. In this paper, we focus on the settings where a possibly large number of instruments and a weak correlation between the instruments and ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Purpose Retinoblastoma (RB) is the most common pediatric ocular cancer, yet population‐based data on survival and risk factors remain limited. This study aimed to describe survival in a large national RB cohort and identify predictors of death and complications.
