Summary

We introduce the (panel) zero-inflated interval regression (ZIIR) model, to investigate GPvisits using individual-level data from the British Household Panel Survey. The ZIIR is particularlysuitable for this application as it jointly estimates the probability of visiting the GP and then,conditional on visiting, the frequency of visits (defined by given numerical intervals in the data). Theresults show that different socio-economic factors influence the probability of visiting the GP and thefrequency of visits.
