Statistics is a well tested element, which provides some basic statistical calculations, such as average, variance, covariance and more. In addition it provides the values of the Standard Normal Distribution and of the T Distribution. The element has one basic procedure that concerns the element as a whole. This is Refresh. Two functions provide constants. These are fN and fT. The following functions calculate requested values and return them: adARMatrixGenerate, dAutocov, dAverage, dCovariance, dDeterminationMeasurement, dServiceDegree, dTheilInequality, dVariance.
