R: Summarise quantities of interest from fitted flexsurvrtrunc...

summary.flexsurvrtrunc {flexsurv} | R Documentation

## Summarise quantities of interest from fitted flexsurvrtrunc models

### Description

This function extracts quantities of interest from the untruncated version of a model with individual-specific right truncation points fitted by `flexsurvrtrunc`. Note that covariates are currently not supported by `flexsurvrtrunc`.

### Usage

    ## S3 method for class 'flexsurvrtrunc'
    summary(
      object,
      type = "survival",
      fn = NULL,
      t = NULL,
      quantiles = 0.5,
      ci = TRUE,
      se = FALSE,
      B = 1000,
      cl = 0.95,
      ...
    )

### Arguments

`object` | Output from `flexsurvreg` or `flexsurvspline`, representing a fitted survival model object.
`type` | `"survival"` for survival probabilities. `"cumhaz"` for cumulative hazards. `"hazard"` for hazards. `"rmst"` for restricted mean survival. `"mean"` for mean survival. `"median"` for median survival (alternative to `type="quantile"` with `quantiles=0.5`). `"quantile"` for quantiles of the survival time distribution. Ignored if `"fn"` is specified.
`fn` | Custom function of the parameters to summarise against time. This has optional first argument `t` representing time, and any remaining arguments must be parameters of the distribution. It should return a vector of the same length as `t`.
`t` | Times to calculate fitted values for. By default, these are the sorted unique observation (including censoring) times in the data - for left-truncated datasets these are the "stop" times.
`quantiles` | If `type="quantile"`, this specifies the quantiles of the survival time distribution to return estimates for.
`ci` | Set to `FALSE` to omit confidence intervals.
`se` | Set to `TRUE` to include standard errors.
`B` | Number of simulations from the normal asymptotic distribution of the estimates used to calculate confidence intervals or standard errors. Decrease for greater speed at the expense of accuracy, or set `B=0` to turn off calculation of CIs and SEs.
`cl` | Width of symmetric confidence intervals, relative to 1.
`...` | Further arguments passed to or from other methods. Currently unused.
