Calculate residuals for flexible survival models
Calculates residuals for flexsurvreg or flexsurvspline model fits.
## S3 method for class 'flexsurvreg' residuals(object, type = "response", ...)

Character string for the type of residual desired. Currently only |

Residuals of type = "response" are calculated as the naive difference between the observed survival and the covariate-specific predicted mean survival from predict.flexsurvreg, ignoring whether the event time is observed or censored.
Numeric vector with the same length as nobs(object).
fitg <- flexsurvreg(formula = Surv(futime, fustat) ~ age, data = ovarian, dist = "gengamma") residuals(fitg)
