Confidence Intervals on lmList Coefficients
Description
Confidence intervals on the linear model coefficients are obtained for each lm
component of object
and organized into a three dimensional array. The first dimension corresponding to the names of the object
components. The second dimension is given by lower
, est.
, and upper
corresponding, respectively, to the lower confidence limit, estimated coefficient, and upper confidence limit. The third dimension is given by the coefficients names.
Usage
## S3 method for class 'lmList' intervals(object, level = 0.95, pool = attr(object, "pool"), ...)
Arguments
object | an object inheriting from class |
level | an optional numeric value with the confidence level for the intervals. Defaults to 0.95. |
pool | an optional logical value indicating whether a pooled estimate of the residual standard error should be used. Default is |
... | some methods for this generic require additional arguments. None are used in this method. |
Value
a three dimensional array with the confidence intervals and estimates for the coefficients of each lm
component of object
.
