Statistical Comparision between Conditional Probability

  1. Aug 22, 2008 #1
    Suppose

    X1 Y1 Z1
    0 0 0 (5 times Z1 is 0 for X1=0 and Y1=0)
    0 0 0
    0 0 0
    0 0 0
    0 0 0
    0 1 0
    0 1 0
    0 1 0
    0 1 0
    0 1 0
    0 1 0
    0 1 0
    0 1 1
    0 1 1
    0 1 1
    0 1 1
    0 1 1
    0 1 1
    0 1 1
    0 1 1
    .
    .
    .

    Which is..
    (Same table which is above..)

    X1 Y1 Z1 (Count of Zeros) (Count of Ones)
    0 0 5 2
    0 1 7 8
    1 0 0 10
    1 1 5 1



    X2 Y2 Z2(Count of Zeros) (Count of Ones)
    0 0 10 4
    0 1 14 16
    1 0 0 20
    1 1 10 2

    Finding P(Z1|X1Y1) AND P(Z2|X2Y2)
    HERE it is the same..

    example
    X1 Y1 Z1 (Probability of Zeros)
    0 0 5|7


    X2 Y2 Z2 (Probability of Zeros)
    0 0 10|14

    But what if this is not the case and we have

    X2 Y2 Z2(Count of Zeros) (Count of Ones)
    0 0 7 5
    0 1 12 2
    1 0 2 0
    1 1 1 5

    Than how to know how close is P(Z1|X1Y1) AND P(Z2|X2Y2) using some method..
