Density probability plots show two guesses at the density function of a continuous variable, given a data sample. The first guess is the density function of a specified distribution (e.g., normal, exponential, gamma, etc.) with appropriate parameter values plugged in. The second guess is the...

We present a framework for statistical analysis of discrete event systems which combines tools such as simulation of marked point processes, likelihood methods, kernel density estimation and stochastic approximation to enable statistical analysis of the discrete event system, even if...

This paper reports findings from a study of changes in Mâori income levels and income dispersion between 1997 and 2003. Data from Statistics New Zealand’s Income Survey are used to describe and evaluate the main changes in the Mâori income distribution in this period, which was marked by...

This paper reports findings from a study of changes in Maori income levels and income dispersion between 1997 and 2003. Data from Statistics New Zealand's Income Survey are used to describe and evaluate the main changes in the Maori income distribution in this period, which was marked by...

Variable bandwidth kernel density estimators increase the window width at low densities and decrease it where data concentrate. This represents an improvement over the fixed bandwidth kernel density estimators. In this article, we explore the use of one implementation of a variable kernel...

By using nonparametric methods, this paper estimates the distribution of both household and size-adjusted real income in Italy between 1987–1998. Because of data sparseness in the distribution, an adaptive bandwidth is used, while to account for sample design a weighting variable is...

In this paper we look at the distribution of wages to examine the extent and cause of the increasing wage inequality in Mexico over the last two decades (1984 to 2000). To understand the causes of the increase in inequality over time we do a counterfactual analysis. We find that over the last...

In this study we look at distribution of wages to examine the extent and cause of the increasing wage inequality in Mexico over the two decades encompassing 1984 and 2000. To understand the causes of the increase in inequality over time we do a counterfactual analysis. We find that over the last...
