Kruskal-wallis' nonparametric analysis of variance. in matlab

The following Matlab project contains the source code and Matlab examples used for kruskal-wallis' nonparametric analysis of variance. . Kruskal-Wallis' nonparametric analysis of variance test the difference among groups and it is applicable for equal or unequal sample sizes and if there are tied ranks. This file uses both the chi-squared and F approximations.

Cochran q test in matlab

The following Matlab project contains the source code and Matlab examples used for cochran q test. H = COCHRANQTEST(X) performs the non-parametric Cochran's Q-test on the hypothesis that the K columns of N-by-K matrix have the same number of successes and failures.

Anderson-darling k-sample procedure to test whether k sampled populations are identical. in matlab

The following Matlab project contains the source code and Matlab examples used for anderson-darling k-sample procedure to test whether k sampled populations are identical. . 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.

Local linear kernel regression in matlab

The following Matlab project contains the source code and Matlab examples used for local linear kernel regression. This is the local linear version of the kernel smoothing regression function: http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=19195&objectType=FILE The local linear estimator improves the regression behaviour near the edges of the region over which the data have been collected.

Mcnemar's exact test. in matlab

The following Matlab project contains the source code and Matlab examples used for mcnemar's exact test. . This m-file performs the conditional as well as the Chi-squared corrected for discontinuity McNemar's exact test for two dependent (correlated) samples that can occur in matched-pair studies with a dichotomous (yes-no) response.
