Pagerank and Alexa

I noticed several weeks ago, when my Page Rank went from 4 to 5, that my Alexa Traffic Rank went from 1,000,000+ to 950,937. My theory, these are one and the same. Page Rank according the Google Toolbar would then be given by 10-log10(Alexa Traffic Rank). You can test it out. The site 'patents.com' has a Page Rank of 7/10, they have a traffic rank of 263,218. Oh wait, that doesn't really work does it. Hmmm... Delphion has a Page Rank of 8/10, and a traffic rank of 43,119. Google has a traffic rank of 4, and a Page Rank of 10/10.

Suppose that a traffic rank of 1,000,000 corresponded to a Page Rank of 5, and that the measure is logarithmic. That would mean that we are looking at log base 15.8489 (approximately). So, to convert traffic rank to Page Rank you would take 10-log(Traffic Rank)/log(15.8489). Let's see if it works. For 'patents.com', I get a Page Rank of ~5.5. For Delphion, I get a Page rank of 6.1. Ok, maybe this doesn't really work. The best way is to plot and see. Maybe it was all just a coincidence. Why should page rank be linked to traffic rank anyway? What was I thinking...

Never mind, just forget about this whole post, there is no relation except for indirect reasons...
