perc: Extract percentiles from a bootstrap sampling distribution.
Description
perc can be used to extract percentiles from the sampling
distribution of a statistic.
Usage
perc(boot.out, p = c(0.025, 0.975))
perc.lm(lm.boot.obj, p)
Arguments
boot.out
Output from either one.boot, two.boot,
or pairs.boot.
p
numeric vector with values in [0, 1].
lm.boot.obj
An object of class "lm.simpleboot",
returned from lm.boot.
Value
For bootstraps which are not linear model bootstraps, perc
returns a vector of percentiles of length
length(p). Linear interpolation of percentiles is done if
necessary. perc.lm returns a matrix of percentiles
of each of the model coefficients. For example, if there are k model
coefficients, the perc.lm returns a length(p) by k matrix.
Details
perc automatically calls perc.lm if boot.out is
of the class "lm.simpleboot" so there is no need to use
perc.lm separately.
