intervals {nlme} | R Documentation

## Confidence Intervals on Coefficients

### Description

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`.

### Usage

    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.

### Value

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