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 shift from one response category to another from sample 1 to sample 2.
When the null hypothesis of symmetry is true, then B will...
Fisher's exact test of 2x4 contingency tables permits calculation of precise probabilities in situation where, as a consequence of small cell frequencies, the much more rapid normal approximation and chi-square calculations are liable to be...
Fisher's exact test of 3x3 contingency tables permits calculation of precise probabilities in situation where, as a consequence of small cell frequencies, the much more rapid normal approximation and chi-square calculations are liable to be...
GMM-GMR is a set of Matlab functions to train a Gaussian Mixture Model (GMM) and retrieve generalized data through Gaussian Mixture Regression (GMR). It allows to encode efficiently any dataset in Gaussian Mixture Model (GMM) through the use of an...
This file, as the Fisher's exact test, performs the exact probability test for a table of frequency data cross-classified according to two categorical variables, each of which has two levels or subcategories (2x2). It is a non-parametric...
The Oregonator model accurately describes the Belousov-Zhabotinsky (BZ) reaction. BZ reaction is an example of oscillating chemical reactions. The simulink file oregonator.mdl solves this classical problem. The values of the parameters used in the...
Anderson and Darling (1952, 1954) introduced a goodness-of-fit statistic to test the hypothesis that a random sample comes from a continuous population with a specified distribution function. It is a modification of the Kolmogorov-Smirnov (K-S)...
This is a robust and accurate circle fit. It works well even if data points are observed only within a small arc. This circle fit was proposed by G. Taubin in article "Estimation Of Planar Curves, Surfaces And Nonplanar Space Curves...
The model simulates asymmetric modulation which can be observed at second scope by zooming the waveform on time axis. In this modulation technique the reference signal is sampled at positive as well as at negative peak of the carrier and held...
Estimates the statistical power of an analysis of variance Model II (random-effects) after it has been performed. It requires the observed F-statistic value, numerator degrees of freedom, denominator degrees of freedom and significance level.
Fisher's exact test of 2x3 contingency tables permits calculation of precise probabilities in situation where, as a consequence of small cell frequencies, the much more rapid normal approximation and chi-square calculations are liable to be...
The package comprises of a graphical utility to place uniform B-spline control points and see how the B-spline is redrawn as control points or control point weights are adjusted, and functions to estimate B-splines with known knot vector, given a...
This is the software to analysis the atomic force microscopy images. Average feature size and area can be calculated using this software.
Steps to follow -
1 - First remove any additional part of the image not included in the...
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...
SSRLSWAM is a combination of SSRLS and stochastic gradient method . It exploits the concept of forgetting factor d?TÂ¬ that may be required due to model uncertainty, presence of unknown external disturbances, time-varying nature of observed...
A simple simulation Model for DC DC step-down buck converter, the model allows measurments of output current/voltage, capacitor current, diode current. Ripples in each measurment can be observed very accurately using the scope
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 Square test to determine whether the...
The model simulates three phase inverter with symmetric PWM modulation in which reference is sampled at the positive peak of the carrier and is held constant till the next positive peak of the carrier appears. The model demonstrates symmetric...
Fleiss'es kappa is a generalization of Scott's pi statistic, a statistical measure of inter-rater reliability. It is also related to Cohen's kappa statistic. Whereas Scott's pi and Cohen's kappa work for only two raters, Fleiss'es kappa works for...
superlos will calculate mho and whether a target was observed given a terrain and array of observer&targets lats/lons/altitudes.
For a single value call the two have similar performance (1x to 2x faster), asymptotes around 40x... |
