Acknowledgement for strel and ewblft
The strel survival analysis algorithm was originally based on code written by Professor Jacques Estève, Service de Biostatistique, Hôpitaux de Lyon. It was later re-written in STATA, and its capabilities substantially extended, by Michael Hills, Andy Sloggett, Bianca De Stavola and Bernard Rachet.
The algorithm has not been formally published, but it has been extensively beta-tested, and was the analytic engine for a substantial monograph on cancer survival in England and Wales, for which many thousands of analyses were done.
