When I first heard that cases were missing I thought “can’t be an Excel problem, the rows run out at 1,048,576 which is bigger than even total cases”. I never thought they’d have a case per COLUMN. Unbelievable. And yes: Excel columns end at 16,384 aka “XFD”.

In the UK the number of cases rose rapidly. But the public – and authorities – are only learning this now because these cases were only published now as a backlog. The reason was apparently that the database is managed in Excel and the number of columns had reached the maximum.

Yesterday, @GiuseppeArena and Marlyne, two PhD-students of our group, attended the IOPS winter conference at Leiden University. We listened to some interesting talks from IOPS PhD students that presented their research. We also presented our own work with a poster!

Due to the similarity of their names, two statisticians (Box & Cox) decided to write a paper together. It has been cited 12747 times.

De kampioen in 2018 moet 2 Champions League-voorrondes overleven, nummer 2 zelfs 3. Bekerwinnaar 2 EL-voorrondes, nummer 3 en 4 zelfs 3.
