is an option for SurvivalModelFit and other functions that specifies the range over which simultaneous confidence intervals and bands are computed.


  • ConfidenceRange affects values of properties related to simultaneous confidence intervals and bands.
  • Possible settings for ConfidenceRange include:
  • Alluse the range of noncensored data
    Fulluse the full range of the data
    {tmin,tmax}explicitly set the confidence range
  • The values tmin and tmax can be any real numbers such that tmin<tmax.
  • For a survival model with estimation points ep, the setting Full is equivalent to the setting {Min[ep],Max[ep]}.
  • The setting All is equivalent to the setting {Min[nc],Max[nc]}, where nc are the endpoints of noncensored and interval-censored data values.
