%description
Implements the EM algorithm with one-step Gradient Descent method to
estimate the parameters of the Block-Basu bivariate Pareto distribution
with location and scale. We also found parametric bootstrap and asymptotic
confidence intervals based on the observed Fisher information of scale and
shape parameters, and exact confidence intervals for location parameters.
Details are in Biplab Paul and Arabin Kumar Dey (2023)
