1 | genItemParameter(type, parms, quantity = 1, truncate.b = c(-Inf, Inf))
|
type |
Either "a" for the item discrimination or "b" for the item difficulty |
parms |
vector of length two. If type = "a", parms must be setup such that a ~ U(parms[1], parms[2]). For type = "b", parms must be such that b ~ N(parms[1], parms[2]). |
quantity |
number of item parameters to generate |
truncate.b |
vector of length 2 containing the limits for the difficulty distribution |
scalar containing one item parameter
