Mann-Kendall is a non-parametric statistical test to determine the existence or absence of a trend at a given statistical significance. The slope of the line describing the trend could still be determined using a least-squares fit (or other suitable method) after the determination of whether a trend exists. ________________________________ From: Denis Bogan <[log in to unmask]> To: [log in to unmask] Sent: Thu, July 8, 2010 5:09:37 PM Subject: Re: [SKIVT-L] Nice Work Wes Yes. Nice work. I do have a curiosity question. I am unfamiliar with the Mann-Kendall test but since it yields a straight line fit I am wondering what is the advantage over a straight line lease squares fit. This would also give correlation coefficients. You must have tried it. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - SkiVt-L is brought to you by the University of Vermont.
