regMin: Artificial Data: Regular Minimality In Non-canonical Form

Description Usage Format Note References See Also Examples


Artificial data of fictitious ‘discrimination probabilities’ among 10 fictitious stimuli.




The regMin data frame consists of 10 rows and 10 columns, representing the fictitious stimuli presented in the first and second observation area, respectively. Each number, a numeric, in the data frame is assumed to give the relative frequency of perceivers scoring ‘different’ to the row stimulus ‘followed’ by the column stimulus.


This dataset is artificial and included for illustrating regular minimality in the non-canonical form. It differs from the artificial data noRegMin only in the entry in row \#9 and column \#10.
