ConfidenceLevel

ConfidenceLevel

is an option for LinearModelFit and other fitting functions that specifies the level to use in various confidence and prediction intervals and bands.

Details

  • ConfidenceLevel affects values of properties related to confidence intervals.
  • The default setting gives 95% confidence intervals.
  • The value should be a number between 0 and 1.
  • For certain types of models, model[…][prop,ConfidenceLevel->c] can be used to extract properties for a specified confidence level. »
