Is it possible to draw a venn diagram with more than 3 vars? I've tried and it seems impossible to me:
with 2 vars the distance between AB is a factor of the % explained. Add the 3rd var, C by using trigonometry (cosine law) when AC and BC are the sides of the triangle with a value the size of the % explained. Adding a 4th seems impossible because maybe because of my my limited trig. the excel spreadsheet I wrote for 3 vars is: http://members.rogers.com/weighted/venn2.xls Not sure if that link is active, I can email it..
