Lorentz

Physics::Lorentz::Transformation Perl module contains representation of poincare transformations. SYNOPSIS use Physics::Lorentz; my $rotation = Physics::Lorentz::Transformation->rotation_euler( $alpha, $beta, $gamma ); my $vector = Physics::Lorentz::Vector->new([$t, $x, $y, $z]); my...

The Gini coefficient is a measure of the inequality of a distribution (often used for income or wealth distributions). The Lorentz curve is a graphical representation of this inequality which is intimately related to the Gini coefficient. The program is straightforward to use. Please consult the... Platforms: Matlab

The Relativity on Rotated Graph Paper Model displays Minkowski spacetime diagrams on rotated graph paper. The worldlines of three inertial observers carrying horizontal light clocks and the resulting clock ticks are drawn. Each clock consists of two mirrors a constant distance d away from an...

It includes numerous features designed to save you time, prevent analysis errors, and help you make better decisions. An integrated... Platforms: Windows

StatAssist displays graphs and related properties of more than 40 probability distributions. This application will save you time and prevent calculation errors if your work or study involves the use of continuous or discrete distributions. It allows to quickly select a distribution of interest,... Platforms: Windows

The Extended GARCH Toolbox estimates a variety of GARCH models with different distributions and for any order of ARCH (p) and GARCH (q) effects.The supported models are:GARCH: Bollerslev (1986)GJR-GARCH: Glosten et al. (1993) EGARCH: Nelson (1991) NARCH: Nonlinear ARCH: Engle and Bollerslev... Platforms: Matlab

The Toolbox forecasts the volatility of a (mxn) vector of data and from a variety of in-built / non-in-built GARCH models with various distributions, as well as the univariate RiskMetrics. The toolbox also estimates a number of Volatility Forecast Loss Functions and if selected Value-at-Risk for... Platforms: Matlab
