eXTenDed Output: Either
This function implements a standard ordinal adequacy test for the
nosof94 CIRP. Specifically, a model passes this test if
the mean errors (averaged across blocks), obey the following:
I < II < [III, IV, V] < VI
Note that '[III, IV, V]' indicates that the these three problems can be in any order of difficulty (or all be of equal difficulty), as long as all three are harder than Problem 2 and all three are easier than Problem 6.
Alternatively, by setting
TRUE, this function
returns the mean classification error by Problem type.
xtdo=FALSE, this function returns TRUE if the ordinal
adequacy tests are passed, and FALSE otherwise.
xtdo=TRUE, this function returns a summary matrix,
containing mean errors (across blocks) for each of the six problem
