Coefficients for ordinal data

• Goodman and Kruskal's gamma
• Podani's measure of discordance

Coefficients for ratio scale data

• Correlation
• Bray - Curtis
• Ruzicka
• Similarity ratio
• Horn
• City block metric
• Mean character difference

Coefficients for mixed data

These coefficients allow the simultaneous appearance of presence/absence, nominal, ordinal and ratio-scale type in the data, and missing scores are also tolerated. Ordial variables are treated as described by Podani in Taxon 1999.
