Simple function to calculate melt rates in meter water equivalent per year for a digital elevation model (DEM) based on positive degree days factor (PDD) using seasonal variation.User can specify factors: mean annual temperature, PDD_ice, seasonal variation in degrees and year length.Approach...

Estimates the exact statistical power of a performed Student's t test about mean(s). Here, according to Winer (1970) we use the exact power by the noncentral cumulative distribution function. It recalls you the statistical result of the test you should have arrived. Inputs:t - Student's t...

The geometric double-entity model method (GDEM) is proposed to gives far-near degrees between clusters (namely, GE distances), which integrate the absolute distance between nearest sample sets and the dense degrees of border regions of two clusters. GE distances are measured based on the...

Design of a robust digital controller with PPR toolboxThis script shows the basic steps for the "digital two degrees of freedom controller" (2DOF) design with the PPR toolbox.The illustration of our methodology is based on a difficult plant control. To get a 2DOF controller, only 2 "high level"...

Doornik-Hansen (1994) introduce a multivariate version of the univariate omnibus test for normality of Shenton and Bowman (1977), based on the transformed skewness and kurtosis. Due that the skewness and kurtosis are not independently distributed and the kurtosis approaches very slowly to...

This file performs the Stuart-Maxwell's test for all the marginal homogeneity (i.e. across all the categories simultaneously) for each of the two sample times (nominal samples). Obviously, it need a square KxK table.It is a non-parametric statistical test. The test was proposed by Stuart (1955),...
