bfa.boot1.ls {bifurcatingr} | R Documentation |
This function performs single bootstrapping of the least squares estimators
of the autoregressive coefficients in a bifurcating autoregressive (BAR)
model of any order p
as described in Elbayoumi & Mostafa (2020).
bfa.boot1.ls(z, p, burn = 5, B, boot.est = TRUE, boot.data = FALSE)
z |
a numeric vector containing the tree data |
p |
an integer determining the order of bifurcating autoregressive model to be fit to the data |
burn |
number of tree generations to discard before starting the bootstrap sample (replicate) |
B |
number of bootstrap samples (replicates) |
boot.est |
a logical that determines whether the bootstrapped least squares estimates of the autoregressive coefficients should be returned. Defaults to TRUE. |
boot.data |
a logical that determines whether the bootstrap samples should be returned. Defaults to FALSE. |
boot.est |
a matrix containing the bootstrapped least squares estimates of the autoregressive coefficients |
boot.data |
a matrix containing the bootstrap samples used |
