Thanks for posting this. I’m happy to see that the results for R were 
generally excellent, and almost always better than for the three other 
software packages.

But there were a few cases where R did not turn out to be the winner.
Rather surprising that Ox was better than R for computing the 
autocorrelation coefficient for two of the datasets, given its terrible 
results for the standard deviation. Anybody have any ideas why?
