Statistical Comparision
Posted:
Jul 21, 2011 5:05 AM


Given two finite strings of numbers a1,.. a_n and b1,.. b_n what's a good way to measure how close or similar they are?
sqr sum(j=1,n) (a^2  b^2)/n ?
Are there other measures?
How would you measure the closeness or similarity if one string is shorter than the other?
What weight or bias would be put on one missing number? On two missing numbers? Is there an established statistical method for handling this type of problem?
