A statistical analysis used for count data is to compare the proportions of a binary outcome of interest for two or more groups.This m-file it is an implemented alternative to the Marascuillo's test and identifies significant pairwise contrasts that this last one does not. If the previously...

This quantity measures how much the entire regression function changes when the i-th observation is deleted. Should be comparable to F_p,n-p: if the 'p-value' of D_i is 50 percent or more, then the i-th point is likely influential: investigate this point further. Cook's distance (D_i) is an...

From the covariance matrices (without data), groups size vector and a significance level (default = 0.05), the homogeneity covariance matrices are testing by the Box's M, it gives a Chi-square or F approximation in function of the groups sample-size.Outputs are the Box's M statistic,...

This m-file performs the Cochran's Q test for multi-way tables which each variable has two levels, that is, for 2x2...x2 tables. It is used to test the homogeneity of the one-dimensional margins. So, Cochran's Q test is a nonparametric test examining change in a dichotomous variable across more...

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...

The purpose of the GUI is to smooth a given signal. The GUI fetches a variable called d-de?yd-deOao from the base workspace. On opening, the variable y is plotted on the axis. When the user slides the slider the smoothed data will be plotted. As the user moves the slide, a P value is changed and...

Bonferroni-Holm (1979) correction for multiple comparisons. This is a sequentially rejective version of the simple Bonferroni correction for multiple comparisons and strongly controls the family-wise error rate at level alpha. It works as follows:1) All p-values are sorted in order of smallest to...

Sphericity is an assumption of repeated measure ANOVA. It means that the variance-covariance structure of the repeated measure ANOVA follows a certain pattern. Sphericity is, in a nutshell, that the variances of the differences between the repeated measurements should be about the same....

Permutation or randomisation tests are a useful alternative to more standard parametric tests for analysing experimental data. They have the advantage of making no distributional assumptions (such as Normality)about the data, while remaining as powerful as more standard tests. The t-test assumes...

The Anderson-Darling test (Anderson and Darling, 1952) is used to test if a sample of data comes from a specific distribution. It is a modification of the Kolmogorov-Smirnov (K-S) test and gives more weight to the tails than the K-S test. The K-S test is distribution free in the sense that the...

Fligner-Policello is a non-parametric test of two combined random variables with continuous cumulative distribution. It is a robust rank-order test of treatment effects for populations which assumes neither normality nor equal variances (Behrens-Fisher problem). It does one assumption, which is...
