answermat |
A matrix of informant answers to a fixed set of questions. The matrix should have n rows and m columns, where n is the number of informants and m is the number of questions. The element in row i and column j should be the answer provided to question j, by informant i. All questions should have the same number of possible responses. |
Each question in answermat
should have the same number of possible responses.
comp |
Maximum-likelihood estimates of the competence scores |
key |
Estimate of the answer key |
conv |
Indication of convergence – a value of 0 means convergence; anything else means failure |
val |
The value of the negative log likelihood function at the solution |
