Dear all,
I have two matrices lets call them A and B. Each of which is a 100 x 3
matrix. What I do is take the corresponding row from each matrix and form
100 2 x 3 tables. If we call the column sums for each 2 x 3 n1, n2 and n3, I
would like to compute the following probability:
Basically the number of (n1 = a, n2 = b) in all the tables divided by the
number of tables. Its the probability that a table has a particular column
total.
So if A was
0 2 3
0 2 3
1 2 4
2 3 3
B was
1 0 3
1 0 2
1 2 4
2 3 3
The 2 x 3 tables would be:
0 2 3
1 0 3
Totals (1,2) # first 2 totals
0 2 3
1 0 2
Totals (1,2)
1 2 4
1 2 4
Totals (2,4)
2 3 3
2 3 3
Totals (4,6)
The expected probabilities I should get are:
0.5, 0.5, 0.25 and 0.25 for each of the 2 x 3 tables.
Any help is greatly appreciated.....
