Cox–Snell residuals

Statistics

Residuals introduced in 1968 by Sir David Cox and E. Joyce Snell, for assessing the validity of a survivor function (see hazard rate) that has been proposed for a set of survival data. The value of the survivor function depends on the time, t, and on one or more parameters estimated by the vector θ̂. The Cox–Snell residual r_j, corresponding to time t_j, is given by $Cox–Snell residuals$ where is the value of the estimated survivor function at time t_j. If the model is correct, then the residuals should have an exponential distribution with mean 1.
