Analysis of progression-free survival data using a discrete time survival model that incorporates measurements with and without diagnostic errorSally Hunsberger
National Cancer Institute, Biostatistics Research Branch, Rockville, MD, USA
Clin Trials 7:634-42. 2010..The second method is considered to be the reference standard but is expensive, time consuming, and logistically difficult. The first method has measurement error associated with it, but, it is less expensive and easier to obtain...
