"Readers should note that Peterson does not carry out TOB adjustments based on documented changes in observation time (which USHCN users might assume). Instead Peterson has used a procedure attributed to DeGaetano BAMS 2000, which purports to estimate observation time based on the properties of the data itself. The DeGaetano procedure, as with so many of these recipes, is not a statistical procedure known to statistical civilization off the island. You can’t go to a statistics textbook and learn its properties. There is no systematic presentation of DeGaetano-adjusted TOBS series against USHCN adjusted series."

I really don't know how any fair reading here eleicits the response you gave. Peterson used this data to assert that there is no UHI. You assert that he is entitled to that claim based on the data that contradicts his assertion after he massages it with a non-statistical procedure. Not inspiring confidence in either assertion Cog.
