Confidence Intervals on lmList Coefficients
Usage
intervals(object, level, pool)
Arguments
object
|
an object inheriting from class lmList , representing
a list of lm objects with a common model.
|
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
attr(object, "pool") .
|
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.Value
a three dimensional array with the confidence intervals and estimates
for the coefficients of each lm
component of object
