Part Worth Estimates

Outpatients in Segment 2 give higher satisfaction ratings to private facilities, while those in segments 3, 5 and 6 give higher ratings to other types of facilities (e.g. nurse, paramedic, midwife, and traditional practitioner). Additionally, outpatients in Segment 4 give higher ratings because of the shorter waiting time while those in Segment 5 do not mind spending more and travel to facilities located in Java.
