The goal of this project is to document and improve computational statistics capabilities and resource utilization within the Department of Statistics. Specifically, we look at the commonly used software Matlab [13] and alternative approaches to its use with GNU Octave [2] and Condor [9, 12]. By providing concrete examples of the process of modifying long-running simulation code from Matlab to ...

Recent advances in the implementation of spatial econometrics model estimation techniques have made it desirable to compare results, which should correspond between implementations across software applications for the same data. These model estimation techniques are associated with methods for estimating impacts (emanating effects), which are also presented and compared. This review constitutes...

MOTIVATION Scatterplots of microarray data generally contain a very large number of dots, making it difficult to get a good impression of their distribution in dense areas. RESULTS We present a fast and simple algorithm for two-dimensional histogram smoothing, to visually enhance scatterplots. AVAILABILITY Functions for Matlab and R are available from the corresponding author.

Soil erosion by water is a widespread phenomenon throughout Europe and has the potentiality, with his on-site and off-site effects, to affect water quality, food security and floods. Despite the implementation of numerous and different models for estimating soil erosion by water in Europe, there is still a lack of harmonization of assessment methodologies. Often, different approaches result in ...

Multi-dimensional arrays are among the most fundamental and most useful data structures of all. In C++, excellent template libraries exist for arrays whose dimension is fixed at runtime. Arrays whose dimension can change at runtime have been implemented in C. However, a generic object-oriented C++ implementation of runtime-flexible arrays has so far been missing. In this article, we discuss our...

This paper presents an overview ofthe FALCON MATLAB-to-Fortran 90 compiler. FA~CON is a programming environment for the development of high-performance scientific programa. It combines static and dynamic inference methods to translate MATLAB programa into Fortran 90. The statit inference is supported with advanced value propagation techniques and symbolic algorithms for subscript analysis. The ...

The electrocardiogram is a diagnostic tool that measures and records the electrical activity of heart in exquisite detail. This will get differ from the normal recordings, if there is any heart disease. We have taken into account the R-R interval based diseases. For this many methods are available to extract the information from the recorded ECG signal. Among them ‘SO and CHAN’ and ‘PAN and TOM...
