%description
Simulation of several fractional and multifractional processes. Includes
Brownian and fractional Brownian motions, bridges and Gaussian Haar-based
multifractional processes (GHBMP). Implements the methods from Ayache,
Olenko and Samarakoon (2025) <doi:10.48550/arXiv.2503.07286> for
simulation of GHBMP. Estimation of Hurst functions and local fractal
dimension. Clustering realisations based on the Hurst functions. Several
functions to estimate and plot geometric statistics of the processes and
time series. Provides a 'shiny' application for interactive use of the
functions from the package.
