variogramfit performs a least squares fit of various theoretical variograms to an experimental, isotropic variogram. The user can choose between various bounded (e.g. spherical) and unbounded (e.g. exponential) models. A nugget variance can be modelled as well, but higher nested models are not...

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...

The Central Limit Theorem (CLT) states that the sample average of N i.i.d. random variables approaches the normaldistribution.This script displays the probability density function of the sample average of N i.i.d variables with respect to N. The variables can be distributed according to a chi-2,...
