Goodness-of-fit problem for errors in nonparametric regression: Distribution free approach

This paper discusses asymptotically distribution free tests for the classical goodness-of-fit hypothesis of an error distribution in nonparametric regression models. These tests are based on the same martingale transform of the residual empirical process as used in the one sample location model. This transformation eliminates extra randomization due to covariates but not due the errors, which is intrinsically present in the estimators of the regression function. Thus, tests based on the transformed process have, generally, better power. The results of this paper are applicable as soon as asymptotic uniform linearity of nonparametric residual empirical process is available. In particular they are applicable under the conditions stipulated in recent papers of Akritas and Van Keilegom and M\"uller, Schick and Wefelmeyer.Comment: Published in at http://dx.doi.org/10.1214/08-AOS680 the Annals of Statistics (http://www.imstat.org/aos/) by the Institute of Mathematical Statistics (http://www.imstat.org

Asymptotically distribution-free goodness-of-fit testing for tail copulas

Let $(X_1,Y_1),\ldots,(X_n,Y_n)$ be an i.i.d. sample from a bivariate distribution function that lies in the max-domain of attraction of an extreme value distribution. The asymptotic joint distribution of the standardized component-wise maxima $\bigvee_{i=1}^nX_i$ and $\bigvee_{i=1}^nY_i$ is then characterized by the marginal extreme value indices and the tail copula $R$. We propose a procedure for constructing asymptotically distribution-free goodness-of-fit tests for the tail copula $R$. The procedure is based on a transformation of a suitable empirical process derived from a semi-parametric estimator of $R$. The transformed empirical process converges weakly to a standard Wiener process, paving the way for a multitude of asymptotically distribution-free goodness-of-fit tests. We also extend our results to the $m$-variate ($m>2$) case. In a simulation study we show that the limit theorems provide good approximations for finite samples and that tests based on the transformed empirical process have high power.Comment: Published at http://dx.doi.org/10.1214/14-AOS1304 in the Annals of Statistics (http://www.imstat.org/aos/) by the Institute of Mathematical Statistics (http://www.imstat.org

From laggard to leader: explaining offshore wind developments in the UK

Offshore wind technology has recently undergone rapid deployment in the UK. And yet, up until recently, the UK was considered a laggard in terms of deploying renewable energy. How can this burst of offshore wind activity be explained? An economic analysis would seek signs for newfound competitiveness for offshore wind in energy markets. A policy analysis would highlight renewable energy policy developments and assess their contribution to economic prospects of offshore wind. However, neither perspective sheds sufficient light on the advocacy of the actors involved in the development and deployment of the technology. Without an account of technology politics it is hard to explain continuing policy support despite rising costs. By analysing the actor networks and narratives underpinning policy support for offshore wind, we explain how a fairly effective protective space was constructed through the enroling of key political and economic interests

Elimination of lubricants in industries in using self-lubricating wear resistant coatings based on MoS2

The problem that has been haunting for long manufacturing industries (automotive, aerospace, domestic appliance and electronics) is the lubrication. Most processes are impossible without lubrication, otherwise wear and galling will occur. On the other hand, many lubricants are toxic and some lubricants are even flammable, and therefore the use of lubricants is a big environment, safety and health concern. This paper demonstrates how innovative self-lubricated coating such as MoS2/Titanium composite coatings can be used to solve these problems and are suitable for the specific requirements with characteristics such as low frictional coefficient, high wear resistance and low cost. For example, demand coatings such as MoS2/Titanium composite coatings is increasing, therefore forming and cutting process can be performed “dry” without use additional lubricants, that is, the oil based lubricants can be eliminated from processes. The benefits of MoS2/Titanium composite coatings are both ecological and economical. The ecological side is obvious. The economical benefits can be obtained from the elimination of the direct costs of lubricants and the application apparatus, from longer tool life and less tool maintenance, from improved quality of machined parts as well as from the indirect costs of parts cleaning and waste disposal. Industrial results from forming and cutting processes will be presented and understanding analysis will be performed. Parameters such as life-time, cutting force, surface finishing… will be correlated to laboratory friction and wear tests as well as microstructure observations

Report on industrial lands focus groups

87 pp. Bookmarks supplied by UO. Tables, appendices. Published July 15, 1998. Captured January 13, 2008.Davis & Hibbitts, Inc. (DHI) is pleased to present a summary of key points based on focus group research conducted for a consortium of organizations working on a regional industrial lands strategy. The purpose of the research was to solicit opinions about industrial land availability and industry location considerations from six perspectives â geographic, warehousing/ distribution, business park/flex space, manufacturing, large campus industrial, and land use/environment/agriculture. This focus group research is part of a larger, broader effort to reach consensus on an industrial lands strategy for the region. The Port of Portland is leading this planning effort, along with the Oregon Economic Development Department, Portland Development Commission, Columbia River Economic Development Council, Commercial Real Estate Economic Coalition, Metro, and Portland General Electric. The full report presents in much more detail the key ideas and themes that emerged from the discussions which may be useful in deciding what additional research and planning needs to be done. Because this was a qualitative study, the information describes, rather than quantifies, the variety of views among focus group participants.
