SurvivalDiagnostics | R Documentation |
These are primarily convenience functions for the RcmdrPlugin.survival package, to produce diagnostics for coxph
and survreg
models in a convenient form for plotting via the package's GUI.

crPlots.coxph
is a method for the crPlots
function in the car package, to create component+residual (partial-residual) plots, using residuals.coxph
and predict.coxph
in the survival package.
testPropHazards
is essentially a wrapper for the cox.zph
function in the survival package.
MartingalePlots
creates null-model Martingale plots for Cox regression models, using the residuals.coxph
function in the survival package.
dfbeta.coxph
and dfbetas.coxph
provide methods for the standard dfbeta
and dfbetas
functions, using the residuals.coxph
function in the survival package for computation. plot.dfbeta.coxph
and plot.dfbetas.coxph
are plot methods for the objects produced by these functions.
dfbeta.survreg
, dfbetas.survreg
, plot.dfbeta.survreg
and plot.dfbetas.survreg
are similar methods for survreg
objects.
Most of these function create graphs and don't return useful values; the dfbeta
and dfbetas
methods create matrices of dfbeta and dfbetas values.
