ON THE ASYMPTOTIC EFFICIENCY OF GMM [PDF]
Econometric Theory, 2013 The efficiency of the generalized method of moment (GMM) estimator is addressed by using a characterization of its variance as an inner product in a reproducing kernel Hilbert space. We show that the GMM estimator is asymptotically as efficient as the maximum likelihood estimator if and only if the true score belongs to the closure of the linear space ...

CGMVAE: Coupling GMM Prior and GMM Estimator for Unsupervised Clustering and Disentanglement [PDF]
IEEE Access, 2021 Impressive progress has been recently witnessed on deep unsupervised clustering and feature disentanglement. In this paper, we propose a novel method on top of one recent architecture with a novel explanation of Gaussian mixture model (GMM) membership, accompanied by a GMM loss to enhance the clustering.

Productivity and Performance: A GMM approach [PDF]
Oxford Bulletin of Economics and Statistics, 2022 AbstractIn this paper we propose a single‐step generalized method of moments (GMM) approach to estimate a production function with multiple quasi‐fixed and variable inputs as well as productivity and inefficiency. Our approach relies on the system consisting of the production function, the first‐order conditions of expected profit maximization with ...

DO BARRIERS TO DIGITAL SERVICES TRADE HAMPER ECONOMIC GROWTH? EVIDENCE FROM A CROSSCOUNTRY ANALYSIS
Buletin Ekonomi Moneter dan Perbankan, 2023 This study examines the relation between trade barriers on digital services and economic growth for a panel of 44 nations from 2014 to 2020. Using the system generalised method of moments estimator and accounting for other factors, we find that trade ...

GMM with Weak Identification [PDF]
Econometrica, 2000 Summary: This paper develops asymptotic distribution theory for generalized method of moments (GMM) estimators and test statistics when some or all of the parameters are weakly identified. General results are obtained and are specialized to two important cases: linear instrumental variables regression and Euler equations estimation of the CCAPM ...

Two-Path GMM-ResNet and GMM-SENet for ASV Spoofing Detection
ICASSP 2022 - 2022 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2022 The automatic speaker verification system is sometimes vulnerable to various spoofing attacks. The 2-class Gaussian Mixture Model classifier for genuine and spoofed speech is usually used as the baseline for spoofing detection. However, the GMM classifier does not separately consider the scores of feature frames on each Gaussian component. In addition,
