intervals.lmList {nlme} | R Documentation |
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.
## S3 method for class 'lmList': intervals(object, level, pool, ...)
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") .
|
... |
some methods for this generic require additional arguments. None are used in this method. |
a three dimensional array with the confidence intervals and estimates
for the coefficients of each lm
component of object
.
