Dennis J. Low Hydrologist U.S.Geological Survey - WRD 215 Limekiln Road New Cumberland, Pennsylvania 17070 (717) 730-6959 I have been running censored Kendall on Minitab, and more recently on R because of the large data size (about 4,000 samples). I have begun to compare the two results and am confused about why the results do not agree. Listed below are two runs for each method on the same dataset where N = 1447: Results from R slope [1] 6.527546 intercept [1] 162.4725 tau [1] 0.08137884 p [1] 2.356061e-06 True = censored data False = non-censored data Results from Minitab S -6875.00 tau -0.00657152 taub -0.0108607 z -0.457711 pval 0.647160 1 = censored data 0 = non-censored data Why don't they agree on anything? I was surprised that R does not present a taub which I believe takes into account ties. I thought p and pval were basically the Pearson's result which indicated significance. What else am I missing?
