Hi! I have a list of data points and I wish to use the Kolmogorov-Smirnov statistic to decide whether they look gaussian. Has anyone done this in Mathematica? What it is: The Kolmogorov-Smirnov statistic compares the cumulative distribution function of your data with the cumulative distibution function of a gaussian and finds the biggest difference between the two functions. It then tells you how probable it is to get a difference that big or bigger, assuming that the data is gaussian. We can also use this to test for distributions other than the gaussian. Typically you look up a table in the back of a statistics book to get the probability, but I need Mathematica to calculate it for me. thanks Robert. -- ************************************************************** Robert McLaughlin http://ciips.ee.uwa.edu.au/~ram/ C.I.I.P.S. ph 61-9- 380 1769 Dept E.
