Abstract : The objectives of the analysis were (1) to determine the error ellipse associated with impact prediction, and (2) to determine the error ellipsoid associated with the prediction of spatial positions (q-dimensional/k-family), by specifying the dimensionality (eigenvalues) and orientation (eigenvectors) of the diagonalized error volume. A q-dimensional error ellipsoid is defined in a prediction function space and centered about the true prediction point. For each volume, there is a definite probability that a sample prediction point will be within the region. This probability is defined by integration of the density function over the error volume.
