An approximation of the exact distribution of the Wilcoxon test for symmetry by means of an Edgeworth series is derived. Probabilities are computed for sample sizes N = 10(1)26(2)42(3)48,50,100, and ...

The normal distribution is the probability distribution that plots all of its values along a symmetrical bell curve, with the highest probabilities centered around the mean value and tapering out ...

Non-parametric procedures, based on the empirical characteristic function, are proposed for estimating the centre δ of a symmetric distribution and for testing the hypothesis of symmetry around an ...

Forecasting for any small business involves guesswork. You know your business and its past performance, but you may not be comfortable predicting the future. Using Excel is a great way to perform what ...
