One sample jackknife

Basic resampling. Supply the data and statistic to resample.

Keywords
nonparametric
Usage
jackknife(data, statistic, args.stat = NULL, label = NULL, statisticNames = NULL, trace = FALSE)
Arguments
data
vector, matrix, or data frame.
statistic
a function, or expression (e.g. mean(myData, trim = .2).
args.stat
a list of additional arguments to pass to statistic, if it is a function.
label
used for labeling plots (in a future version).
statisticNames
a character vector the same length as the vector returned by statistic.
trace
logical, if TRUE an indication of progress is printed.
Value

a list with class "jackknife" that inherits from "resample", with components:
observed
the value of the statistic for the original data.
replicates
a matrix with R rows and p columns.
n
number of observations in the original data, or vector of length 2 in two-sample problems.
p
length(observed).
R
number of replications.
seed
the value of the seed at the start of sampling.
call
the matched call.
statistics
a data frame with p rows, with columns "observed", "mean" (the mean of the replicates), and other columns appropriate to resampling; e.g. the bootstrap objects have columns "SE" and "Bias", while the permutation test objects have "Alternative" and "PValue".
There are functions for printing and plotting these objects, in particular print, plot, hist, qqnorm, quantile.

Note

The current version only handles a single sample.
