This article evaluates the numerical accuracy of Ox object-oriented matrix programming language. It uses the Standard Reference Datasets (StRD) for estimation accuracy, the ELV DOS program for statistical distribution accuracy, and the DIEHARD battery of randomness tests for random number...

This article reviews the object-oriented features of the Ox matrix programming language. We discuss object-oriented programming in general and give econometric examples coded in Ox. We also discuss some useful built-in classes that come with the Ox distribution.

This paper employs a new econometric technique to estimate the core inflation in Turkey measured as the shifting means in levels between 1955 and 2014. Using monthly series, we determine the number of shifts using the BIC, the hv-block cross-validation, the Lin-Teräsvirta parameter constancy...

In this paper we analyze the limiting properties of the estimated parameters in a general class of asymmetric volatility models which are closely related to the traditional exponential GARCH model. The new representation has three main advantages over the traditional EGARCH: (1) It allows a much...

Recent research has revealed a wealth of information about the microeconomics of currency markets and thus the determination of exchange rates at short horizons. This information is valuable to us as scientists since, like evidence of macroeconomic regularities, it can provide critical guidance...

The present article offers a careful description of empirical identification of possible multiple changes in regime. We apply recently developed tools designed to select among regime-switching models among a broad class of linear and nonlinear regression models and provide a discussion of the...

Within a flexible parametric regression framework (Hamilton, 2001) we provide further evidence on the existence of a nonlinear component in the quarterly growth rate of the US real GNP. We implement a battery of new tests for neglected nonlinearity based on the theory of random fields (Dahl and...

Low birthweight outcomes are associated with considerable social and economic costs, and therefore the possible determinants of low birthweight are of great interest. One such determinant which has received considerable attention is maternal smoking. From an economic perspective this is in part...
