Description Usage Arguments Value Author(s)
This function can be used to analytically determine the expected
probability that a DOMC item is solved correctly, as opposed to the
simulation approach used in workDOMCItem
1 2  domc_analytical(accuracy, criterionVector, n_options = NULL, item = NULL,
sd_sol = 1)

accuracy 
Accuracy value of an assumed test taker 
criterionVector 
The test taker's criterion vector; pass as in

n_options 
number of answer options in the MC item; only pass if item parameter is not specified 
item 
Can be passed instead of n_options  pass a vector of 0 and 1, which indicate the sequence of answer options, in particular the solution position 
sd_sol 
Standard deviation of the solution distribution. Distractor SD is always 1 
The expected probability that an item is solved correctly
