Least squares regression of y on x assumes that the x variate is measured without error, and minimizes the sum of squared vertical distance between the data points y and the fitted regression line. Regression of x on y minimizes the horizontal distances. Adcock [1] in 1878 suggested minimizing the sum of squared horizontal + vertical distances to the predicted values. However the idea of Adcock...

Automatic estimation of velocities from GPS coordinate time series is becoming required to cope with the exponentially increasing flood of available data, but problems detectable to the human eye are often overlooked. This motivates us to find an automatic and accurate estimator of trend that is resistant to common problems such as step discontinuities, outliers, seasonality, skewness, and hete...

Maintaining a software system resembles renovating a house: it usually takes longer and costs more than planned. Similarly to a house owner identifying potential problems before renovation, a software owner should assess maintainability of software before renovating or extending it. To measure maintainability one often applies metrics, associating software artifacts with numbers. Unfortunately,...

BACKGROUND Per United Nations' Sustainable Development Goals, Nepal is aspiring to achieve universal and equitable access to safe and affordable drinking water and provide access to adequate and equitable sanitation for all by 2030. For these goals to be accomplished, it is important to understand the country's geographical heterogeneity and inequality of access to its drinking-water supply and...

Index numbers of prices and quantities are estimated in the framework of a two-way analysis of variance, based on the ideas of H. Theil and K. Banerjee. Topics include aggregation, multidimensional indices, and non-spherical errors. The method is applied to the commodity exports of developing nations. Copyright (c) 1997 Eric Blankmeyer

While software metrics are commonly used to assess software maintainability and study software evolution, they are usually defined on a micro-level (method, class, package). Metrics should therefore be aggregated in order to provide insights in the evolution at the macro-level (system). In addition to traditional aggregation techniques such as the mean, recently econometric aggregation techniqu...

This paper outlines the evolution of the theory of economic policy from the classical contributions of Frisch, Hansen, Tinbergen and Theil to situations of strategic interaction. Andrew Hughes Hallett has taken an active and relevant part in this evolution, having contributed to both the development and recent rediscovery of the classical theory, with possible relevant applications for model bu...
