Web\beta(a, b) for :math:`x >= 0`, :math:`a > 0`, :math:`b > 0`, where :math:`\beta(a, b)` is the beta function (see `scipy.special.beta`). `betaprime` takes ``a`` and ``b`` as shape parameters. The probability density above is defined in the 'standardized' form. To shift and/or scale the distribution use the ``loc`` and ``scale`` parameters. WebTime synchronization is essential for node localization, target tracking, data fusion, and various other Wireless Sensor Network (WSN) applications. To improve the estimation accuracy of continuous clock offset and skew of mobile nodes in WSNs, we propose a novel time synchronization algorithm, the Rao-Blackwellised (RB) particle filter time …
