series.bootstrap: Series bootstrap

In dplRCon: Concordance for Dendroclimatology

Description

This function calculate the bootstrapped replicated series for calculating concordance

Usage

series.bootstrap(data.boot, stat, R, names.stat, aver.by.tree.input)

Arguments

data.boot	Data matrix containing standardized ring width indices from which the bootstrapped replicates are calculated.
stat	A function giving the statistics that are to be calculated
R	The number of bootstrapped replicates
names.stat	the names of the statistics contained in function "stat"
aver.by.tree.input	This is a True/False. If True then averages tree series, then average tree means. If False then average all series

Value

org.stat	The original input statistics
boot.stat	The statistics of the bootstrapped replicates, c('mean','median')
bias	The bias of the boot.stat
std.error	The standard error of boot.stat
boot.series.mean	The bootstrapped replicates mean series
boot.series.std	The bootstrapped replicates standard deviation series

Examples

## Not run: #Subset "near-pith" is the material within 0 -20cm from the estimated pith
spline200.sub0.20.n   <- TruncSeriesPithoffset( ring.raw, ring.stand, dbh.po.nc, c(1,200))
boot.0.20   <-  series.bootstrap( spline200.sub0.20.n$sub.series.stand, stat, 999,
   names.stat, aver.by.tree = FALSE)
## End(Not run)
