AVERAGE SQUARED DISTANCE

dissimilarity [0, 1]; same as binary euclidean distance of
http://149.170.199.144/multivar/dist.htm
Usage: for binary data.
CA MEASURE OF ASSOCIATION
http://www.psych.cornell.edu/Darlington/crosstab/table3.htm
CA (for "conditional association") is a modification of OGE that in
principle can be defined for tables of any size, but in practice is computed
easily only for 2x2 tables, so we explain it in those terms.
CRAMER PHI MEASURE OF ASSOCIATION
http://www.psych.cornell.edu/Darlington/crosstab/table3.htm
The Cramer phi and phi2 are simple transformations of the familiar
Pearson chi-square statistic for testing association in a frequency table.
BINARY DICE DISTANCE
http://www.iro.umontreal.ca/~nie/IR-book/Ch.3.html
Dissimilarity coefficient that satisfies the triangle inequality
Usage: for binary data.
OGE MEASURE OF ASSOCIATION
http://www.psych.cornell.edu/Darlington/crosstab/table3.htm
OGE has a frequency interpretation that many users will find more
appealing than the ratio-scale interpretation of phi2.
