Stellar kinematics is concerned with the movements of stars in the vicinity of the Sun, as well as with some aspects of the structure of our Galaxy in the same vicinity. This book discuses mathematical techniques developed for these studies, some classical and employed since the 19th century, such as least squares, and others of more recent origin and not included in other texts dedicated to stellar kinematics, including total least squares, in use since the 1980s, and semi-definite programming, developed since the 1990s. Other useful methods test for the randomness of data and ways to...

This monograph is concerned with overdetermined systems, inconsistent systems with more equations than unknowns, in scientific data reduction. It is not a text on statistics, numerical methods, or matrix cOmputations, although elements of all three, especially the latter, enter into the discussion. The reader I have in mind is a scientist or engineer who has gathered data that he or she wants to model by a mathematical system, perhaps linear, perhaps nonlinear, and solve to obtain the best estimates, in some sense of the term "best," of various parameters. Because the calculations will be...
