As explained, the different procedures share the same premises regarding taxonicity and dimensionality, and the expectations of the different taxometric procedures are derived as straightforward consequences. Note that if a premise is true, then the consequences are expected to be observable. The different procedures are therefore not independent and cannot provide cumulative evidence. The procedures differ with respect to statistical power possibly because different summary statistics are evaluated, and have been reported to be differentially sensitive to the selection of cut points and other procedural choices, in addition to the characteristics of the data (Walters & Ruscio, 2010). Ruscio (2012) has provided an implementation in R.
