THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

The Design and Analysis of Experiments

According to W. Edwards Deming, American companies require nothing less than a transformation of management style and of governmental relations with industry. In Out of the Crisis, originally published in 1982, Deming offers a theory of management based on his famous 14 Points for Management. Management's failure to plan for the future, he claims, brings about loss of market, which brings about loss of jobs. Management must be judged not only by the quarterly dividend, but by innovative plans to stay in business, protect investment, ensure future dividends, and provide more jobs through improved product and service. In simple, direct language, he explains the principles of management transformation and how to apply them.

Statistical Analysis With Missing Data (2nd ed.) (Book)

This paper presents an introduction to inference for copula models, based on rank methods. By working out in detail a small, fictitious numerical example, the writers exhibit the various steps involved in investigating the dependence between two random variables and in modeling it using copulas. Simple graphical tools and numerical techniques are presented for selecting an appropriate model, estimating its parameters, and checking its goodness-of-fit. A larger, realistic application of the methodology to hydrological data is then presented.

Everything You Always Wanted to Know about Copula Modeling but Were Afraid to Ask

SUMMARY This paper investigates the properties of a semiparametric method for estimating the dependence parameters in a family of multivariate distributions. The proposed estimator, obtained as a solution of a pseudo-likelihood equation, is shown to be consistent, asymptotically normal and fully efficient at independence. A natural estimator of its asymptotic variance is proved to be consistent. Comparisons are made with alternative semiparametric estimators in the special case of Clayton's model for association in bivariate data.

A semiparametric estimation procedure of dependence parameters in multivariate families of distributions

Toute fonction de repartition bidimensionnelle dont les marges sont continues peut etre representee de fcon unique par une copule, c'est-a-dire par une fonction de repartition concentree sur le carre unite et dont les marges sont uniformes. Dans cet article, nous nous interessons a une classe de copules, dites archimediennes, qui permet de representer bon nombre de lois bidimensionnelles connues. Nous donnons des conditions sous lesquelles deux copules de cette classe sont ordonnees stochastiquement et nous examinons les proprietes limites de suites de copules archimediennes. Nous fournissons egalement deux nouveaux exemples de families parametriques de lois bidimensionnelles comprenant comme cas limites les bornes de Frechet et la loi d'independance.



Every bivariate distribution function with continuous marginals can be represented in terms of a unique copula, that is, in terms of a distribution function on the unit square with uniform marginals. This paper is concerned with a special class of copulas called Archimedean, which includes the uniform representation of many standard bivariate distributions. Conditions are given under which these copulas are stochastically ordered and pointwise limits of sequences of Archimedean copulas are examined. We also provide two new one-parameter families of bivariate distributions which include as limiting cases the Frechet bounds and the independence distribution.

An Overview of the Shainin System for Quality Improvement

Small forests in agricultural landscapes are generally thought to be population sinks where the nesting success of Neotropical migrant songbirds is too low to sustain populations. In 1996 and 1997, we assessed the nesting success and productivity of Wood Thrushes ( Hylocichla mustelina) and Rose-breasted Grosbeaks ( Pheucticus ludovicianus) in the Region of Waterloo, a highly fragmented agricultural landscape with 14% forest cover in southwestern Ontario. We located 154 Wood Thrush nests and 63 Rose-breasted Grosbeak nests in 26 small forest fragments (3–14 ha) and 15 large fragments (26–140 ha). We used the Mayfield method to determine nesting success. Across all sites nesting success was 51% for Wood Thrushes and 46% for Rose-breasted Grosbeaks. Nesting success and productivity rates were used in a simple population growth model that suggested that the Wood Thrushes but not the Rose-breasted Grosbeaks were a self-sustaining population. Forest size and distance of nests to the nearest forest edge (measured in five distance classes ranging from 0 to over 100 m) did not significantly affect the nesting success or productivity of either species. Brown-headed Cowbirds (  Molothrus ater) parasitized 47% of all Wood Thrush nests and 10% of all Rose-breasted Grosbeak nests; parasitism significantly reduced Wood Thrush productivity but not that of Rose-breasted Grosbeaks. Our findings challenge the prevailing notion that small woodlots in a farmed landscape are invariably habitat sinks and offer additional incentive for habitat protection in settled landscapes where small forest fragments are often all that remain for conservation purposes.




Resumen: Los bosques pequenos en paisajes agriculturales son generalmente vistos como sumideros poblacionales donde el exito de nidacion de aves canoras neotropicales migratorias es muy bajo como para sostener poblaciones. En 1996 y 1997 evaluamos el exito de nidacion y reproductivo del zorzalito maculado, Hylocichla mustelina y del picogrueso pechirrosado, Pheucticus ludovicianus en la region de Waterloo, un paisaje agricultural altamente fragmentado, con un 14% de la cobertura forestal en el Suroeste de Ontario. Localizamos 154 nidos de zorzales y 63 de picogrueso en 26 fragmentos pequenos de bosque (3–14 ha) y 15 fragmentos grandes (26–140 ha). Utilizamos el metodo Mayfield para determinar el exito de nidacion. A lo largo de todos los sitios el exito de nidacion fue de un 51% para los zorzales y de 46% para los picogruesos. El exito de nidacion y las tasas de productividad fueron usadas en un modelo de crecimiento poblacional simple que sugiere que los zorzales, pero no los picogruesos constituyeron una poblacion autosostenible. El tamano del bosque y las distancias de nidos al borde mas cercano del bosque (medidas en cinco categorias de distancia de 0 a> 100 m) no afectaron significativamente el exito de nidacion ni la productividad de las especies estudiadas. Los vaquero cabecicafe ( molothrus alter) parasitaron 47% del total de nidos de zorzales y 10% de los nidos del picogrueso; el parasitismo redujo significativamente la productividad del zorzalito pero no la del picogrueso. Nuestros resultados contrastan con la idea prevalente de que los lotes pequenos de bosques son habitats sumidero y ofrecen un incentivo adicional para la proteccion de habitats en paisajes habitados donde los fragmentos pequenos de bosque son todo lo que queda para propositos de conservacion.

Nesting Success of Neotropical Migrant Songbirds in a Highly Fragmented Landscape

In industry, process monitoring is widely employed to detect process changes rapidly. However, in some industrial applications observations are censored. For example, when testing breaking strengths and failure times often a limited stress test is performed. With censored observations, a direct application of traditional monitoring procedures is not appropriate. When the censoring occurs due to competing risks, we propose a control chart based on conditional expected values to detect changes in the mean strength. To protect against possible confounding caused by changes in the mean of the censoring mechanism we also suggest a similar chart to detect changes in the mean censoring level. We provide an example of monitoring bond strength to illustrate the application of this methodology.
