collapseConfusionMatrix3x3To2x2

confusion_matrix_3x3

A function to call on the 3x3 confusion matrix to
assign a model's guesses-- 0 predictions tracked in the 2nd column-- to
-1 or 1 counts.

guess_handling_fn

A function to call on the 3x3 confusion matrix to
distribute ties-- 0 correct answers tracked in the 2nd row-- to -1 or 1
counts.

tie_handling_fn

A 3x3 confusion matrix results from predictPair.

Implements various heuristics like Take The Best and
unit-weight linear, which do two-alternative choice: which of
two objects will have a higher criterion? Also offers functions
to assess performance, e.g. percent correct across all row pairs
in a data set and finding row pairs where models disagree.
New models can be added by implementing a fit and predict function--
see vignette. Take The Best was first described in: Gigerenzer, G.
& Goldstein, D. G. (1996) <doi:10.1037/0033-295X.103.4.650>. All
of these heuristics were run on many data sets and analyzed in:
Gigerenzer, G., Todd, P. M., & the ABC Group (1999).
