Extract model coefficients from fitted flexible survival models. This presents all parameter estimates, transformed to the real line if necessary. For example, shape or scale parameters, which are constrained to be positive, are returned on the log scale.
# S3 method for flexsurvreg
coef(object, ...)Output from flexsurvreg or
flexsurvspline, representing a fitted survival model object.
Further arguments passed to or from other methods. Currently unused.
This returns the mod$res.t[,"est"] component of the fitted
model object mod. See flexsurvreg,
flexsurvspline for full documentation of all components.
This matches the behaviour of coef.default for standard R model
families such as glm, where intercepts in regression
models are presented on the same scale as the covariate effects. Note that
any parameter in a distribution fitted by flexsurvreg or
flexsurvreg may be an intercept in a regression model.
