Using the Box-Cox regression model with heteroscedasticity, we examine the size distribution of firms. Analyzing the data set of Portuguese manufacturing firms as in Machado and Mata (2000), we show that our approach compares favorably against the Box-Cox quantile regression method. In...

The demand for real M2 in the Czech Republic is positively influenced by real output and negatively associated with the deposit rate, the koruna/euro exchange rate, and the euro interest rate. The coefficient of real output for the demand for real M1 is insignificant. Hence, depreciation of the...

We propose a family of transformations which, unlike the Box-Cox transformation, can sensibly be applied to variables of either sign which may be near or far from zero. We derive two forms of Lagrange multiplier test for the null hypothesis that the dependent variable has not been transformed...

A hedonic approach is used to study farmland prices in Aragon (Spain). Data over 450 transactions in 33 shires, in 2001 and 2002 are analysed. The marginal values for irrigated vs. non-irrigated land, the productive orientation and the differentiation of production through a Designation of...

Bayesian hierarchical models that characterize the distributions of (transformed) gene profiles have been proven very useful and flexible in selecting differentially expressed genes across different types of tissue samples (e.g. Lo and Gottardo, 2007). However, the marginal mean and variance of...

M1, M2, and M3 demands in Mexico are positively influenced by output and stock prices and negatively associated with the saving rate, the U.S. interest rate, and the expected inflation rate. Peso depreciation affects M1 demand negatively and M2 and M3 demands positively. The log-linear form...

This paper examines the effect of functional form specification on the estimation of technical efficiency using a panel data set of 125 olive-growing farms in Greece for the period 1987–93. The generalized quadratic Box-Cox transformation is used to test the relative performance of...

In this paper we consider a general first-order power ARCH process and, in particular, a special case in which the power parameter approaches zero. These considerations give us the autocorrelation function of the logarithms of the squared observations for first-order exponential and logarithmic...

Unlike the residential market, in office space rental hedonistic price studies are few and far between. This paper sets out to show, for the first time, the application of hedonistic prices for the office rentals in the Paris region, over the 2002-2006 period. We offer a better understand on...
