Hi all,

i'm new R user and i need some help:

i have two vectors (A and B) and i need create another vector (C) from the subtraction of A's values with the B's values. How can i estimate the probability of C's values if i have differents values combinations of A and B that can result in the same value? like 90 -20 = 70 and 91 - 21 = 70.

example:

B = {18      18    18     19      20      21      22      23      24      25      26      27   28....} 
A = {82     83     84     85      85     86       87     88       89      90      91     91    92 ....}

Considering C's values that were computed from different frequencies of the A and B, is it necessary any mathematical convolution to estimated the probability more precisely?

Thanks a lot

Ricardo
