heuristica

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). .
