Digit analysis



6. Digit  analysis:
             The digit analysis is used in a situation when all the identifiers are known in advance.we first transform the identifiers in to numbers using some radix r.Then we examine the digits of each identifier.Some digits having most skewed distributions are deleted.This deleting of digits is continued until the number of remaining digits is small enough to give an address in the range of hash table.Then these digits are used to calculate the hash address.
