## S3 method for class 'mat'
summary(object, k = 10,
digits = max(2, getOption("digits") - 4), ...)
object |
an object of class |
k |
numeric; maximum modern analogues to use to summarise model fits. |
digits |
numeric; the number of significant digits with which to format results. |
... |
arguments passed to or from other methods. |
A list with the components below. The number of analogues used,
k is returned as attribute "k"
.
summ |
a data.frame containing the model fits for training set samples. See notes below. |
tbl |
matrix of summary statistics for an un-weighted model. |
tbl.W |
matrix of summary statistics for a weighted model. |
call |
the matched function call |
quantiles |
the quantiles of the distribution of pairwise
dissimilarities for the training set, for |
The returned component "summ"
contains the following:
the observed responses for the training set samples.
the fitted values of the response for training set samples based on the average of k-closest analogues.
the residuals of the fitted model based on the average of k-closest analogues.
the fitted values of the response for training set samples based on the weighted average of k-closest analogues.
the residuals of the fitted model based on the weighted average of k-closest analogues.
dissimilarity of closest analogue in training set for each training set sample.
smallest residual for an un-weighted model of size
"k"
.
size of model leading to minimal residual,
"minResi"
.
smallest residual for a weighted model of size
"k.W"
.
size of model leading to minimal residual,
"minW.Resi"
