`summary`

methods for class `flexrsurv`

.
Produces and prints summaries of the results of a fitted Relative Survival Model

1 2 3 4 5 6 7 |

`object` |
an object of class "flexrsurv", usually, a result of a call to |

`x` |
an object of class |

`correlation` |
logical; if |

`symbolic.cor` |
logical. If |

`digits` |
the number of significant digits to use when printing. |

`signif.stars` |
logical. If TRUE,'significance stars' are printed for each coefficient. |

`...` |
further arguments passed to or from other methods. |

`print.summary.glm`

tries to be smart about formatting the coefficients, standard errors, etc.
and additionally gives ‘significance stars’ if `signif.stars`

is `TRUE`

.

Correlations are printed to two decimal places (or symbolically): to see the actual correlations
print `summary(object)$correlation`

directly.

The dispersion of a GLM is not used in the fitting process, but it is needed to find standard errors. If dispersion is not supplied or NULL, the dispersion is taken as 1 for the binomial and Poisson families, and otherwise estimated by the residual Chisquared statistic (calculated from cases with non-zero weights) divided by the residual degrees of freedom.

The function summary.flexrsurv computes and returns a list of summary statistics of the fitted flexible relative survival model given in `object`

.
The returned value is an object of class "`summary.flexrsurv`

", which a list with components:

`call` |
the " |

`terms` |

`coefficients` |
the matrix of coefficients, standard errors, z-values and p-values. |

`cov` |
the estimated covariance matrix of the estimated coefficients. |

`correlation` |

`symbolic.cor` |

`loglik` |

`df.residual` |
