Installation
------------
The ``fBb`` package is available on pypi and can be installed using pip
.. code-block:: shell
pip install fBb
How to use this package
-----------------------
Stochastic interpolation
~~~~~~~~~~~~~~~~~~~~~~~~
To use ``fBb`` to interpolate sparse measurement points ``X_i`` at
times ``t_i``
import the multipoint fractional Brownian bridge process with the desired
Hurst parameter ``H`` and the desired time step ``dt`` of the underlying fractional Brownian motion.
.. code-block:: python
from fBb import MFBB
mfbb = MFBB(X_i, t_i, H, dt)
X_bridge = mfbb.bridge()
t_bridge = mfbb.t_fine()
plt.scatter(t_i, X_i)
plt.plot(t_bridge, X_bridge)
plt.show()
