Changes in version 2.1.0 (2024-04-08)                  

The function naming convention was separated with dots (.). It is
modified to use underscore instead ( '_'). For example, the function
"bfa.ls" becomes "bfa_ls". in addition, vignette file is developed and
published with this version.

                 Changes in version 2.0.0 (2023-06-22)                  

NEW FEATURES

Several corrected and uncorrected confidence intervals for the lease
squares estimators of the bifurcating autoregressive model with any
order p are added. The following confidence intervals are available in
the new version (2.0.0):

  - Uncorrected standard normal bootstrap confidence interval.

  - Standard normal bootstrap confidence interval with single bootstrap
    bias correction.
  - Standard normal bootstrap confidence interval with fast double
    bootstrap bias correction.
  - Uncorrected percentile bootstrap confidence interval.
  - Percentile bootstrap confidence interval with single bootstrap bias
    correction.
  - Percentile bootstrap confidence interval with fast double bootstrap
    bias correction.
  - Bias-corrected and accelerated bootstrap confidence interval.

Corrections

  - bfa.scatterplot function that allows to create the scatterplots
    between observations at time t and the lagged observations from the
    given bifurcating autoregressive tree data fixed. Currently, it
    gives correct axes' labels.
