Calculates the scaled partial residuals of a relative survival model

)
rs.zph(fit, sc, transform = "identity", var.type = "sum")
fit |
the result of fitting an additive relative survival model, using
the In the case of multiplicative and transformation models the output is
identical to |

partial residuals calculated by the |

a character string specifying how the survival times should
be transformed. Possible values are |
var.type |
a character string specifying the variance used to scale the
residuals. Possible values are |
an object of class rs.zph
. This function would usually be
followed by a plot of the result. The plot gives an estimate of the
time-dependent coefficient beta(t)
. If the proportional hazards
assumption is true, beta(t)
will be a horizontal line.
