Taschenbuch. Zustand: Neu. Neuware -A regression analysis describes the dependency of random variables in the form of a functional relationship. One distinguishes between the dependent response variable and one or more independent influence variables. There is a variety of model classes and inference methods available, ranging from the conventional linear regression model up to recent non- and semiparametric regression models. The so-called generalized regression models form amethodically consistent framework incorporating many regression approaches with response variables that are not necessarily normally distributed, including the conventional linear regression model based on the normal distribution assumption as a special case. When repeated measurements are modeled in addition to fixed effects also random effects or coefficients can be included. Such models are known as Random Effects Models or Mixed Models. As a consequence, regression procedures are applicable extremely versatile and consider very different problems. In this dissertation regularization techniques for generalized mixed models are developed that are able to perform variable selection. These techniques are especially appropriate when many potential influence variables are present and existing approaches tend to fail. First of all a componentwise boosting technique for generalized linear mixed models is presented which is based on the likelihood function and works by iteratively fitting the residuals using weak learners. The complexity of the resulting estimator is determined by information criteria. For the estimation of variance components two approaches are considered, an estimator resulting from maximizing the profile likelihood, and an estimator which can be calculated using an approximative EM-algorithm. Then the boosting concept is extended to mixed models with ordinal response variables. Two different types of ordered models are considered, the threshold model, also known as cumulative model, and the sequential model. Both are based on the assumption that the observed response variable results from a categorized version of a latent metric variable. In the further course of the thesis the boosting approach is extended to additive predictors. The unknown functions to be estimated are expanded in B-spline basis functions, whose smoothness is controlled by penalty terms. Finally, a suitable L1-regularization technique for generalized linear models is presented, which is based on a combination of Fisher scoring and gradient optimization. Extensive simulation studies and numerous applications illustrate the competitiveness of the methods constructed in this thesis compared to conventional approaches. For the calculation of standard errors bootstrap methods are used. 176 pp. Englisch.

Hardcover. Zustand: vg-. First edition. Folio. 88pp. (text), 72 plates (Volume I), 69pp (text), 56 plates (Volume II). Originally issued in two volumes, here bound in one. Elaborate deluxe binding in pebbled brown leather boards with wood inlays and a large embossed decorative sword and shield image with detailed tooling in gilt and blue lettering. Spine with gilt lettering and raised bands. Blind-stamped dentelles. A luxurious copy. Rare edition of an exceptional work compiling 128 mounted salt prints and albumen photographs, depicting a wide selection of armor for both men and horses, shields and weapons including early fire arms. Volume One contains 72 salt prints and Volume Two contains 33 salt prints and 23 albumen prints. The hundreds of items documented in this early photographic catalog come from the personal collection of Archduke Ferdinand II of Austria and are displayed at Ambras Castle, the Archduke's residence between 1563 and 1595. Ferdinand II founded the Ambras collections of 15th and 16th century arms and armor that had originally been assembled by the Emperor Maximilian I and Archduke Sigismund. This collection became renowned during his own lifetime and he built a specially conceived museum complex to house and display them. The salt prints average 11" x 6" (279 x 229mm) the albumens are as large as 11" x 9" (279 x 229mm.) The prints are mounted on paper and framed with ink. Each photograph is preceded by a cover sheet printed with Roman numerals and a descriptive title. Text in German. Binding with minor sunning and rubbing to extremities. Head of spine at the front hinge lightly chipped. Interior with some foxing preliminary pages and some instances of plate images. Binding and interior very good- condition overall. About the authors: Andreas Groll (1812-1872), was born in Vienna as the son of a man servant. He may have learned photography during his time as a lab assistant at the polytechnic institute - today's Technical University - in Vienna from 1845 to 1853. At that time, the polytechnic institute was the most important place of early photography in Austria because of the presence of professors such as Johann Joseph of Prechtl, Anton of Schroetter (who is said to have encouraged Groll) and particularly the activity of Anton Georg Martin. Groll's early work was daguerreotype. He then turned to salt prints and albumen photographic prints. In cooperation with Eduard von Sacken, Groll's first large special photographic project was to photograph the historical weapons and armors gathered in the imperial collections of the Ambras Castle. (John Hannavy in "Encyclopedia of Nineteen Century Photography") Eduard Freiherr von Sacken (1825-1883 ) was an Austrian heraldist and antiquarian. In 1845, he was the amanuensis (secretary to a scholar) at the Imperial coin and antiquities museum of Vienna (Münz- und Antikenkabinett.) In 1854, he was hired as a curator and in 1871 was appointed director of the museum. Von Sacken published numerous Art-Historical works, but remains mostly renown for his very scholarly work on heraldry. (From A. Bernhard-Walcher: "Eduard Freiherr von Sacken," in: "Österreichisches Biographisches Lexikon 18151950" (ÖBL) Band 9, Verlag der Österreichischen Akademie der Wissenschaften, Wien 1988).

Wien, undated ( before 1869 ), the 8 albumine prints are mounted on 6 boards. The albumine prints represent different views of the original drawings by von Sicardsburg and van der Nüll. Sizes vary between 26 x 38 cm and 50 x 20 cm. Some of the drawings are titled. E.g. ''Rückwärtige Ausicht'' on board n°6. (This is also the print with Groll's name). Other drawings are: Groundfloor, Querschnitt durch die Bühne, Querschnitt, Seitenansicht (aussen). .All prints are mounted on contemporary boards. (62 x 46 cm). The boards are a bit dustsoiled, some of the prints are more or less faded. The boards are stamped with the collection stamp of Frans Baeckelmans ( 1835 - 1896) . He was an Antwerp (Belgium - Flanders) architect who reputedly designed neo-renaissance buildings partially based on photographic examples of classical renaissance buildings ( e.g. the old court of justice in Antwerp, based on a Baldus picture of the Louvre - this picture also formed part of his collection). The photographer Andreas Groll ( 1812 - 1872) was one of the photography pioneers of the Habsburg empire. Architecture was one of his main intrests. The Wiener Staatsoper ( still standing) was contructed between 1861 and 1869 at the newly constructed Ringstrasse. Its neo-renaissance style must surely greatly have pleased the Antwerp architect collector . This collection is an interesting and early testimony of the use of the newly invention of the art of photography in architectural design.
