Bootstrap object description
Description
Objects of class bootstrap.mat
are a complex containing
many sub-components. This object is described here in more detail.
Details
A large object is returned with some or all of the following depending
on whether newdata
and newenv
are supplied or not.
observed
: - vector of observed environmental values.
model
: - a list containing the apparent or non-bootstrapped
estimates for the training set. With the following components:
estimated
: - estimated values for the response
residuals
: - model residuals
r.squared
: - Apparent R^2 between observed and
estimated values of response
avg.bias
: - Average bias of the model residuals
max.bias
: - Maximum bias of the model residuals
rmse
: - Apparent error (RMSE) for the model.
k
: - numeric; indicating the size of model used in
estimates and predictions
bootstrap
: - a list containing the bootstrap estimates for the
training set. With the following components:
estimated
: - Bootstrap estimates for the response
residuals
: - Bootstrap residuals for the response
r.squared
: - Bootstrap derived R^2 between observed
and estimated values of the response
avg.bias
: - Average bias of the bootstrap derived model
residuals
max.bias
: - Maximum bias of the bootstrap derived model
residuals
rmsep
: - Bootstrap derived RMSEP for the model
s1
: - Bootstrap derived S1 error component for the
model
s2
: - Bootstrap derived S2 error component for the
model
k
: - numeric; indicating the size of model used in
estimates and predictions
sample.errors
: - a list containing the bootstrap-derived sample
specific errors for the training set. With the following
components:
rmsep
: - Bootstrap derived RMSEP for the training set
samples
s1
: - Bootstrap derived S1 error component for training
set samples
s2
: - Bootstrap derived S2 error component for training
set samples
weighted
: - logical; whether the weighted mean was used instead of
the mean of the environment for k-closest analogues
auto
: - logical; whether
"k"
was choosen automatically or
user-selected
n.boot
: - numeric; the number of bootstrap samples taken
call
: - the matched call
type
: - model type
predictions
: - a list containing the apparent and
bootstrap-derived estimates for the new data, with the following
components:
observed
: - the observed values for the new samples —
only if
newenv
is provided
model
: - a list containing the apparent or
non-bootstrapped estimates for the new samples. A list with the
same components as
model
, above
bootstrap
: - a list containing the bootstrap estimates
for the new samples, with some or all of the same components as
bootstrap
, above
sample.errors
: - a list containing the bootstrap-derived
sample specific errors for the new samples, with some or all of
the same components as
sample.errors
, above
