people.cs.pitt.edustrictly stationary, but this is not true for weakly stationary. Weak stationarity usually does not imply strict stationarity as higher moments of the process may depend on time t. If time series fX tgis Gaussian (i.e. the distribution functions of fX tgare all multivariate Gaussian), then weakly stationary also implies strictly stationary.

Similarly, using the stationary and independent increments property, we conclude that B(t)−B(s) has a normal distribution with mean 0 and variance t−s, and more generally: the limiting BM process is a process with continuous sample paths that has both stationary and independent normally distributed (Gaussian) increments: If t 0 ...

In the EKF, the state distribution is ap-proximated by a GRV, which is then propagated analyti-cally through the first-order linearization of the nonlinear system. This can introduce large errors in the true posterior mean and covariance of the transformed GRV, which may

The tailing factor is mea - sured as: T=b/a a represents the width of the front half of the peak, is the width of the back half of the peak. The values are measured at 10 % of the peak height from the b
