water scarcity is today’s world biggest challenge which requires different countries to manage their water resources in the most efficient way. sprinkler irrigation increases water consumption efficiency due to more uniform distribution of water across the field. precision farming is based on the site-specific use of inputs according to soil characteristics and plant needs. one of the main inpu...
Most Irish traditional folk dance music contains two musical themes; the tune begins with one musical theme which is usually repeated, then progresses to another theme with similar musical structure and motives, which is usually also repeated. The first section is typically called the A section while the second is called the B section. Our goal is to understand, at a quantitative level, the mus...
The standard tobit or censored regression model is typically utilized for regression analysis when the dependent variable is censored. This model is generalized by developing a conditional mixture, maximum likelihood method for latent class censored regression. The proposed method simultaneously estimates separate regression functions and subject membership in K latent classes or groups given a...
This paper develops tests for overidentifying restrictions in Factor-Augmented Vector Autoregressive (FAVAR) models. The FAVAR combines a high-dimensional factor model and a conventional VAR for the latent factors. The identification of structural shocks in FAVAR can lead to restrictions on the factor loadings of many variables, so it can involve infinitely many identifying restrictions as the ...
In Section 1.3 of the paper, we presented an unsteady, diffusion-free model to calculate species concentrations and shock speeds in ITP. We also showed (in Figure 2 of paper) comparison of our model with detailed 1-dimensional simulations using SPRESSO [1,2]. Here we describe the numerical procedure to calculate species concentrations in different ITP zones using our diffusionfree model. In Sec...
This paper considers the problem of testing for cross section independence in limited dependent variable panel data models. It derives a Lagrangian multiplier (LM) test and shows that in terms of generalized residuals of Gourieroux, Monfort, Renault and Trognon (1987) it reduces to the LM test of Breusch and Pagan (1980). Due to the tendency of the LM test to over-reject in panels with large N ...
