More statistics to consider

[m-clark]

While I think there is already enough for most needs, we can always add more if they are straightforward to calculate. If so, perhaps this should be an optional argument with default to FALSE.

• Yule/Phi (will not call it Matthews!)
• Tetrachoric correlation (probably not due to heavy lifting)
• AUC (see psych implementation)
• d'
• Peirce's coefficient (because he was awesome)
• Jaccard (still notably used in some disciplines)
• Odds ratio
• Others

Possibly separate correlation coefficients
Preference for those that are zero if statistically independent
