Further to yesterday's blog about Michael J Smith's opinion piece in Pediatrics, telling us not very much, a very interesting observation on it was made here, in post 9 for those who want the specific place.
Some might say that someone as esteemed as Michael J Smith, would have already applied the Bonferroni adjustment. But who says? But if he can't catch blatantly obvious errors in either his maths or percentage evaluations, where's the guarantee he would he have remembered the Bonferroni adjustment?
As a point of interest, I did not know about the Bonferroni adjustment. Not that it would make much difference to me, because years ago, when I researched just how the P value was ascertained in the first place, I quickly realised that any research system which relied on a figure pulled out of a metaphorical magician's hat, didn't inspire ultimate confidence intervals in the first place.
