\code{grtools} provides functions for the following analyses using general recognition theory:

1. Model-based analyses of separability and independence with GRT-wIND for the 2x2 identification experiment (Soto et al., 2015). See \code{\link{grt_wind_fit}} and \code{\link{grt_wind_fit_parallel}}

2. Model-based analyses of separability and independence with traditional GRT models for the 2x2 identification experiment (Ashby & Soto, 2015). See \code{\link{grt_hm_fit}}

3. Summary statistics analysis (i.e. Kadlec's MDSDA; see Kadlec & Townsend, 1992) for the 2x2 identification experiment. See \code{\link{sumstats_micro}} and \code{\link{sumstats_macro}}

4. Summary statistic analysis for the 2x2 Garner filtering task (Ashby & Maddox, 1994). See \code{\link{sumstats_garner}}
