Lagrange Multiplier tests for omitted variables , heteroscedasticity, incorrect functional form and asymmetry in the ordered logit model may be readily calculated using an artificial regression. The proposed artificial ...

Lagrange Multiplier (LM) tests for omitted variables, heteroscedasticity, incorrect functional form, and non-normality in the ordered probit model may be readily calculated using an artificial regression. The proposed ...

LM tests for omitted variables, neglected heteroscedasticity and other mis-specifications in general discrete choice models may be simply and conveniently calculated using an artificial regression. This artificial regression ...

While financial incentives usually have a signifi cant effect on the labor supply of married women
and single mothers, the evidence about the participation elasticity of childless singles, and single males
especially, ...

College graduates tend to earn more than non-graduates but it is difficult to ascertain how much of this empirical association between wages and college degree is due to the causal effect of a college degree and how much ...
This Chapter examines cash dividends and share repurchases in the United States during the period 1990 to 2008. In the extant literature a variety of classical statistical methodologies have been adopted, foremost among ...
Random field regression models provide an extremely flexible way to investigate
nonlinearity in economic data. This paper introduces a new approach to interpreting such models, which may allow for improved inference about ...
Field boundaries are important habitats for birds within the agricultural landscape. In this study, bird surveys
were carried out during the winter and breeding season on nine farms in the east and south-east of
Ireland ...
This paper provides new evidence on the wage gap between informal and formal salary workers
in South Africa, Brazil and Mexico. We use rich datasets that allow us to define informality in a
relatively comparable fashion ...

The objective of this study was to assess the suitability of statistical and the k-C* models to projecting treatment performance of constructed wetlands by applying the models to predict the final effluent concentrations ...

Looking at house price cycles across the OECD since 1970, we find a strong relationship between the size of the initial rise in price and its subsequent fall. Were this relationship to hold for Ireland, it would predict ...
Dewatered alum sludge, a widely generated by-product of drinking water treatment plants using aluminium salts as coagulants was used as main substrate in a pilot on-site constructed wetland system treating agricultural ...

A convenient artifical regression based LM test of non-normality in the probit model is derived using a Gram Charlier type A alternative. The test is simply derived and may be extended to the bivariate probit case. The ...
Murphy, Anthony(University College Dublin. School of Economics, 1994-10)
A simple and convenient artificial regression based LM tests of asymmetry in the logit model is derived. The test does not use the outer product gradient (OPG) form and in thus likely to have fairly good small sample properties.
Murphy, Anthony(University College Dublin. School of Economics, 1994-10)
A simple artificial regression based test of the fit of the binary choice models is derived. the test statistic is likely to have reasonable small sample properties since it is not based on the outer product gradient form ...
Murphy, Anthony(University College Dublin. School of Economics, 1994-11)
A simple artificial regression based on Lagrange Multiplier (LM) test for zero correlation in the censored bivariate probit model is derived. The outer product gradient form of the LM test is not used so the proposed test ...
Murphy, Anthony(University College Dublin. School of Economics, 1994-12)
A simple and convenient LM test of normality in the bivariate probit model is derived. The alternative hypothesis is based on a form of truncated Gram Charlier Type series. The LM test may be calculated as an artificial ...
Non-domestic rates are a tax that is formally levied on the occupiers of non-domestic property in the UK. A study analyzes the effects of changes to business rates on a sample of 2,964 institutionally-owned commercial ...
