intervals function

Confidence Intervals on Coefficients

Confidence intervals on the parameters associated with the model represented by object are obtained. This function is generic; method functions can be written to handle specific classes of objects. Classes which already have methods for this function include: gls, lme, and lmList.

intervals(object, level, ...)

Arguments

• object: a fitted model object from which parameter estimates can be extracted.
• level: an optional numeric value for the interval confidence level. Defaults to 0.95.
• ...: some methods for the generic may require additional arguments.

Returns

will depend on the method function used; see the appropriate documentation.
