Stratified analysis

Image taken from ECHR blog

Now if you happen to have a slight confusion with numbers and if you also happen to have this defect from the earliest age possible, you 'ld be able to sympathise with me right this moment. My evenings in the last week has been spent staring at articles describing numbers and why they mean what they do in that analysis and why we should do this and not that. And how to adjust for this and not that and maybe this may work. Confusing? You bet!! Humbling to find oneself struggling with something basic.

Enough said...now its back to the grind for me:(
