Summarize an lmList Object
Description
The summary.lm
method is applied to each lm
component of
object
to produce summary information on the individual fits,
which is organized into a list of summary statistics. The returned
object is suitable for printing with the print.summary.lmList
method.
Usage
## S3 method for class 'lmList'
summary(object, pool, ...)
Arguments
object |
an object inheriting from class |
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 list with summary statistics obtained by applying summary.lm
to the elements of object
, inheriting from class
summary.lmList
. The components of value
are:

a list containing an image of the |
coefficients |
a three dimensional array with summary information
on the |
correlation |
a three dimensional array with the
correlations between the individual |
cov.unscaled |
a three dimensional array with the unscaled
variances/covariances for the individual |
df |
an array with the number of degrees of freedom for the model
and for residuals, for each |
df.residual |
the total number of degrees of freedom for
residuals, corresponding to the sum of residuals df of all |
fstatistics |
an array with the F test statistics and
corresponding degrees of freedom, for each |
pool |
the value of the |
r.squared |
a vector with the multiple R-squared statistics for
each |

individual |
RSE |

the individual |
terms |
