abstract: Numerical derivatives through finite-difference approximations can be calculated
  using the 'pnd' package with parallel capabilities and optimal step-size selection
  to improve accuracy. These functions facilitate efficient computation of derivatives,
  gradients, Jacobians, and Hessians, allowing for more evaluations to reduce the
  mathematical and machine errors. Designed for compatibility with the 'numDeriv'
  package, which has not received updates in several years, it introduces advanced
  features such as computing derivatives of arbitrary order, improving the accuracy
  of Hessian approximations by avoiding repeated differencing, and parallelising slow
  functions on Windows, Mac, and Linux.
