Chi Square Formula

Moving Least Square(MLS) for 3-dimension Least Square method is common curve fitting approch. But for special some function, the tradiational Least Square method is hard to get enough accurancy dueo to gobal approximation. Moving Least Square(MLS) can fit any differentiable function through local...

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,...

In statistics, the Kruskald-deOCtWallis one-way analysis of variance by ranks (named after William Kruskal and W. Allen Wallis) is a non-parametric method for testing equality of population medians among groups. It is identical to a one-way analysis of variance with the data replaced by their...

Grubb's outlier test can be used to remove one outlier (see deleteoutliers.m by Brett Schoelson). If you decide to remove this outlier, you might be tempted to run Grubbs' test again to see if there is a second outlier in your data. However, if you do this, you cannot use the same rejection...
