We present an algorithm to estimate the two-way fixed effect linear model. The algorithm relies on the Frisch-Waugh-Lovell Theorem and applies to ordinary least squares (OLS), two-stage least squares (TSLS) and generalized method of moments estimators (GMM). The coefficients of interest are computed using the residuals from the projection of all variables on the two sets of fixed-effects. Our a...

R is free, open-source, cooperatively developed software that implements the S statistical programming language and computing environment. The current capabilities of R are extensive, and it is in wide use, especially among statisticians. The sem package provides basic structural equation modeling facilities in R, including the ability to fit structural equations in observed variable models by ...

The main objective of the research was to characterize innovation network and estimate an adoption rate evaluate its relationship with income generation in quinoa producers Cabana. characterization has been carried out using social analysis methodology (SNA), index (IAI) obtained through ordinal measurement scale return level innovations on Producers' estimated two-stage least squares (TSLS) da...

The study examined the factors that influence industrialization in Africa using annual panel data from 1990 to 2018. To avoid problems of endogeneity, we employed Two-Stage Least Square (TSLS) approach estimate significant determinants industrialization. We found foreign direct investment, total natural resources, and financial development significantly positively predicted Trade openness had a...

Asymptotic expansions are made for the distributions of the Maximum Empirical Likelihood (MEL) estimator and the Estimating Equation (EE) estimator (or the Generalized Method of Moments (GMM) in econometrics) for the coefficients of a single structural equation in a system of linear simultaneous equations, which corresponds to a reduced rank regression model. The expansions in terms of the samp...

Understanding the relationship between grading practices and student evaluations is especially important in higher education because of the increasing importance of this instrument in the promotion process. If evaluations can be increased by giving higher grades, then they are a flawed instrument for the evaluation of teaching. Further, this process may be contributing to the inflation of grade...

In order to test the performance of new neutron thermal scattering law (TSL) evaluations it is desirable have experimental data that highly sensitive TSL and provides high fidelity information on energy dependent evaluations. Three relevant experiments are discussed including: accurate total cross section measurements, die-away experiments, leakage experiments. The setups results reviewed examp...

Abstract Direct payments are regarded as a suitable instrument to safeguard jobs in the agricultural sector. However, empirical findings date do not unambiguously support this expectation. We further empirically investigate research question on dairy farms with focus family work. Using spatial regression discontinuity design, we rely upon selection unobservables assumptions. The Swiss direct sy...
