prob R Documentation
Estimate the probability of a correct response
Description
This function works because we know we have a Rasch model, otherwise the
function would be just a bit more complicated. Provides the probability of a
correct response for a given item difficulty, b, and a given ability
estimate, theta. Note that theta is typically passed as a
vector of abilities and so a vector of probabilities is returned.
Usage
prob(b, theta)
Arguments
b
The item difficulty estimate
theta
The person ability estimate. This is the theta estimate
from get_person_estimates() (not the RIT score).
