Arguments
data
array of data, if a 2D array then each row is considered as
one multivariate observation
statistic
function, when sim is set to parametric,
the first argument to statistic must be the data. For
each replicate a simulated dataset returned by ran.gen
will be passed. In all other cases,
R
number of bootstrap replicates
sim
string, indicates the type of simulation. The default value is
"ordinary". Other possible values are parametric, balanced,
permutation, and antithetic. Importance resampling is
specified by including impor
stype
string, indicates what the second argument of statistic
represents. The default value is i for indices. Other
possible values are f for frequencies and w for weights.
It is not used when sim is set t
strata
vector of integer, specifies the strata for multi-sample
problems. This may be specified for any simulation, but is
ignored when sim is set to parametric. When strata is
supplied for a nonparamet
L
vector of influence values evaluated at the observations. This is
used only when sim is set to antithetic. If not supplied, they
are calculated through a call to empinf. This will use the
infinitesimal jackknife
m
the number of predictions which are to be made at each bootstrap
replicate. This is most useful for (generalized) linear models.
This can only be used when sim is ordinary. m will usually be
a single integer but
weights
array of importance weights. If a vector then it should
have as many elements as there are observations in the
input data. When simulation from more than one set of
weights is required, weight
ran.gen
function, used only when sim is set to parametric. It
describes how random values are to be generated. It should
be a function of two arguments. The first argument should
be the observed data a
mle
secong argument to ran.gen, typically these will be maximum
likelihood estimates of the parameters. For efficiency mle is
often a list containing all of the objects needed by ran.gen
which can be calculat
simple
boolean, can only be set to TRUE if sim is set to
ordinary, stype is set to I and n is set to 0. Otherwise
it is ignored and generates a warning. By default a n by R
index array is created which c
...
other named arguments for statistic which are passed unchanged
each time.
