Zusammenfassung
This note demonstrates an application of a multilevel multinomial
model. We use that model to analyse interviewer effects on various
components of unit nonresponse to a face-to-face survey: refusals
and noncontacts. The model allows for an analysis of these two interviewer
effects and a possible connection between both at the same time.
Our results show that both the chances for refusals as for noncontacts
are subject to interviewer effects. We also find some evidence for
a relation between both interviewer effects: interviewers who obtain
more refusals are also more likely to report noncontacts. That result
is however at least partly dependent on an outlier, an interviewer
with a high number of refusals and noncontacts.
