Every so often I get a question on if and how the Venn Diagram routine I
made for Stata can also draw the Venn Diagrams such that the overlapping
areas are sized according to the proportions of data.
E.g. factor a only is represented by 10%, factor b only by 35%, factor a
and b by 30% and neither a or b by 25 %. Then the areas of the total
graph should be the same percentage (proportion) of the total area.
Currently I intend to work on upgrading Venndiag to Stata 9 during the
autumn and should someone wish to collaborate on this let me know
directly to "jl at epidata.dk"
Apologies for having added a vcard to my earlier mail today on the
newcomer aspect. I thought I had set up the mail to not include this in
outgoing mails. (no comments on this please).
