Hi, currently, i am a bit lost. i want to calculate the discriminative power of items in my questionnaire. i have found the psych package which should contain that sort of thing, but i cant find it in there. by what name does it go? it probably does not help that i have got onlygerman books on the subject, so i am not good with the names of the methods...
