内容简介：In the latest version ofThe desired properties from the original maximum entropy bootstrap function
In the latest version of
meboot (v 1.4-8)
on CRAN, the function
mebootSpear
was introduced. Below is a gentle introduction to its capabilities and a link to a reference paper with further applications to improved Monte Carlo simulations.
The desired properties from the original maximum entropy bootstrap function
meboot
were retained, while incorporating the additional argument
setSpearman
. The original function created bootstrap replicates with unit rank-correlations to the original time-series,
setSpearman
relaxes this condition.
AirPassengers
The following example will demonstrate the
mebootSpear
rank-correlation results from the average of 1,000 bootstrap replicates of the
AirPassengers
dataset.
library(meboot)
output <- mebootSpear(AirPassengers, setSpearman = 0, xmin = 0)$rowAvg
cor(output, AirPassengers, method = "spearman")
[1] 0.01695065
