Thanks for your comment. It is quite interesting and to some extent worrying that you get different results from the same dataset i.e. povcal.net. Log linear or normal linear, the peak remains at 1.64-65 a day in our distribution function for 2010. I will send you by email the excel file with our numbers so you can compare them with yours. Figure 1a might not completely show the tails well at the upper end (and lower end) of Pen’s parade and hence you should not jump to conclusions. Anyway, have a look at the excel file I am sending you and let’s get together and exchange notes, ideas and future work?
