dear members,
I'm looking for information about "RELATIVE DISSIMILARITY INDEX", as could
be the English for italian "indice relativo di dissomiglianza", which
compares two frequency distribution and is given by half the sum of the
absolute differences between each relative frequency. It reaches 1 for the
maximum dissimilarity between the two distributions and 0 for their
identity. G. Leti: Statistica Descrittiva, Il Mulino ed., pgg. 525 &
following.
I'd like to know about
1) softwares that compute it automatically (I didn't found it in SAS Proc
Freq)
2) how to calculate (if possible and meaningful) confidence intervals
kind regards
