This m-file performs the Bowker's test for symmetry. It is an extension of the McNemar test to a KxK situation. There are now K response categories for the two dependent samples.The null hypothesis is that the probabilities in the square table satisfy symmetry or that there is no sifnificant...

This test performs an odds ratio inference for k strata of 2x2 tables. Mantel and Haenszel (1959) proposed an approximate test of the null hypothesis which specifies that within each stratum, the success probabilities are equal. This is the same to test that there is a common odds ratio and it is...

CHI2RAYLTEST: Single sample Pearson Chi Square goodness-of-fit statistical test to examine a null hypothesis of Rayleigh Channel.H=CHI2RAYLTEST(X,ALPHA) performs the particular case of Pearson Chi Squaretest to determine whether the null hypothesis of a Rayleigh channel realization is a...

The Double Slit Wave-Particle Duality Model demonstrates how matter and light display both wave- and particle-like properties in single and double slit experiments. The simulation shows a detector screen placed behind an aperture with one or two open slits. Particles (electrons or photons) pass...

MISFITS is a program to evaluate the goodness of fit of a model to an alignment in phylogeny reconstruction. It offers a look back at the alignment to pinpoint to site patterns that do not fit to the model and the resulting tree (thereafter referred to as the tree-model). MISFITS then introduces...

Pintail is a tool for identifying anomalies, including chimeras, within 16S rDNA sequences. The program works by comparing evolutionary distances between a query and subject sequence over the length of the 16S rRNA gene (small subunit rRNA), by employing a sampling window of specified size,...

This application allows you to study the factors involved in an experiment with a Fabry-Perot interferometer. It lets you visualize the result of the multiple-wave interferences produced in the interferometer cavity when an extended source emitting two extremely close wavelengths is used. In this...

Zero-G is a racing game that is inspired by F-Zero X and by Gran Turismo. From F-Zero X, tracks are defined by a curve that can twist and turn through the air. There are loops and tunnels and inversions that give the game a non-realistic feel. However, I love the time trials of Gran Turismo,...
