ADS in ADE-4 : Spatial Data Analysis

Posted on January 30, 2003 by Dan Gezelter

ADS in ADE-4is a package devoted to multiscale analysis of spatial point patterns. The proposed methods are based on the analysis of inter-point distances, which necessitate the location of individuals in (x;y) coordinates within a given study area. These methods, which allow the detection of complex multiscale structures within plots of any shape, are well-adapted to plant ecology.

The R Project for Statistical Computing

Posted on October 10, 2002 by Dan Gezelter

R is `GNU S’ – A language and environment for statistical computing and graphics. R is similar to the award-winning S system, which was developed at Bell Laboratories by John Chambers et al. It provides a wide variety of statistical and graphical techniques (linear and nonlinear modelling, statistical tests, time series analysis, classification, clustering, …).

Zeta – a program for calculating zeta potential from mobilities or apparent zeta potentials

Posted on August 21, 2002 by Dan Gezelter

Zeta can be used to calculate zeta potentials for ka > 6 from electrophoretic mobilities measured at the stationary level or from apparent zeta potentials displayed by zetameter (estimated by Smoluchowski equation). Apparent mobilities measured at 3 different levels in a rectangular electrophoretic cell (aspect ratio > 4) can be used to calculate the zeta potential (parabola method).
