Tests whether a model output passes the ordinal adequacy criterion for
Matrix containing model output. The matrix must have the
same format, row order, and column names, as that returned by
eXTenDed Output: Either
This function implements the Wills et al. (2016) ordinal adequacy
test for the
shin92 CIRP. Specifically, a model passes
this test if response accuracy is higher for novel items from the
size-10 condition than novel items from the size-3 condition.
Alternatively, by setting
TRUE, this function
returns the summary model predictions reported by Wills et al. (2016).
xtdo=FALSE, this function returns TRUE if the ordinal
adequacy test is passed, and FALSE otherwise.
xtdo=TRUE, this function returns a summary matrix. The rows
are the two category sizes, the columns are the three principal stimulus
types (old, prototype, new), and the values are predicted accuracy
