H all,
I have a 6 x 3 matrix. The last column is simply the sum of of the first two
rows.
x1 x2 x3
1 2 3
2 1 3
1 0 1
2 2 4
2 1 3
2 1 3
0 0 0
I want to create a column of probabilities p, such that for each row, I want
to find the probability of x1=k and x3 = n divided by the probability that
x3 = n.
So I should end up with a column of probabilities:
1/4, 3/4, 1/7, 1/7, 3/4, 3/4, 1/7

Thanks,
Jim.
