.... The construction of a confidence region starts with an estimate of the mean and the covariance matrix. The shape, size, and orientation of the confidence region depend on the correlation structure of the variables in the data and the sample size. For a normal or Gaussian distribution, the confidence region...

..., the mean and covariance matrix of the distribution of the pose error are analytically determined. Then, the expectation propagation of the multivariate Gaussian and saddlepoint approximation method are employed to calculate the probabilities of kinematic reliability under the rectangular and spherical safe...
