Pearson Correlation Coefficient

normxcorr2_general computes the normalized cross-correlation of matrices TEMPLATE and A. The resulting matrix C contains correlation coefficients and its values may range from -1.0 to 1.0.Limitations of normxcorr2:The documentation of normxcorr2 states that, "The matrix A must be larger than the...

It generates a stochastic field on a squared space. Samples are created by Latin hypercube sampling and the spatial correlation is performed by an algorithm based on Cholesky decomposition. Example inside.

The Gini coefficient is a measure of the inequality of a distribution (often used for income or wealth distributions). The Lorentz curve is a graphical representation of this inequality which is intimately related to the Gini coefficient. The program is straightforward to use. Please consult the...
