Dear Perl monks,
I have a successive question. Now how do I select two columns at random, count ONLY all the z's common to both columns.
I would like to repeat this say 10 times and finally get the mean of all counts (i.e 10 random selection).
It gets more complicated. In the next round of random selection, I want to pick 3 columns and count the z's common to all of them, repeat this ten times. Do this .... until say n = 18 columns! getting the mean at each at the end of each instance!
At the moment I have no idea on how to go about it!
A hint would be really appreciated
Thanks
