The necessity to publish the second edition of this book arose when its
third German edition had just been published. This second English
edition is there- fore a translation of the third German edition of
Parameter Estimation and Hypothesis Testing in Linear Models, published
in 1997. It differs from the first English edition by the addition of a
new chapter on robust estimation of parameters and the deletion of the
section on discriminant analysis, which has been more completely dealt
with by the author in the book Bayesian In- ference with Geodetic
Applications, Springer-Verlag, Berlin Heidelberg New York, 1990. Smaller
additions and deletions have been incorporated, to im- prove the text,
to point out new developments or to eliminate errors which became
apparent. A few examples have been also added. I thank Springer-Verlag
for publishing this second edition and for the assistance in checking
the translation, although the responsibility of errors remains with the
author. I also want to express my thanks to Mrs. Ingrid Wahl and to Mrs.
Heidemarlen Westhiiuser who prepared the second edition. Bonn, January
1999 Karl-Rudolf Koch Preface to the First Edition This book is a
translation with slight modifications and additions of the second German
edition of Parameter Estimation and Hypothesis Testing in Linear Models,
published in 1987.
