Peter Vijn commented on Vincent Granville's blog post Why Zipf's law explains so many big data and physics phenomenons
"Thanks for this Vincent. Is Fig.1 complete? It only shows Company and number of members at the moment. I expect rank number, Zipf's outcome and perhaps a chart with the Zipf-fit as well."

Peter Vijn commented on Vincent Granville's blog post Black-box Confidence Intervals: Excel and Perl Implementation
"While I'm studying this post a bit deeper, after first read I noticed the cause of the (...must be too...) big discrepancy between the model-free and classic CI's: It's not the individual sample's SD and/or CI that is studied…"
