Al. Booth et Se. Satchell, THE HAZARDS OF DOING A PHD - AN ANALYSIS OF COMPLETION AND WITHDRAWALRATES OF BRITISH PHD STUDENTS IN THE 1980S, Journal of the Royal Statistical Society. Series A. Statistics in society, 158, 1995, pp. 297-318
The paper examines the completion and withdrawal rates for British PhD
students, by using the 1986 national survey of 1980 graduates. The st
atistical analysis is carried out in a competing risks framework, base
d on the distributional assumptions of the generalized gamma family. T
he problem of thresholding of completion data is also addressed. We fi
nd considerable variability of completion rates across disciplines, ge
nder and individuals' employment status while undertaking PhD research
