Specification Testing in Nonlinear Time Series with Long-Range Dependence
Get PDFThis paper proposes a model specification testing procedure for parametric specification of the conditional mean function in a nonlinear time series model with long–range dependence. An asymptotically normal test is established even when long–range dependence is involved. In order to implement the proposed test in practice using a simulated example, a bootstrap simulation procedure is established to find a simulated critical value to compute both the size and power values of the proposed test.Asymptotic theory, Gaussian process, nonlinear time series, long-range dependence, parametric specification
Characterization for high dynamic range imaging
No full textIn this paper we present a new practical camera characterization technique to improve color accuracy in high dynamic range (HDR) imaging. Camera characterization refers to the process of mapping device-dependent signals, such as digital camera RAW images, into a well-defined color space. This is a well-understood process for low dynamic range (LDR) imaging and is part of most digital cameras — usually mapping from the raw camera signal to the sRGB or Adobe RGB color space. This paper presents an efficient and accurate characterization method for high dynamic range imaging that extends previous methods originally designed for LDR imaging. We demonstrate that our characterization method is very accurate even in unknown illumination conditions, effectively turning a digital camera into a measurement device that measures physically accurate radiance values — both in terms of luminance and color — rivaling more expensive measurement instruments
Great River Reading Series: Melissa Range
No full textOn April 12, 2022 poet Melissa Range read from her work at Winona State University as part of WSU’s John S. Lucas Great River Reading Series.
Melissa Range was born and raised in East Tennessee. She received a BA from the University of Tennessee–Knoxville in 1995, an MFA from Old Dominion University in 1998, and an MTS from Emory University in 2005. She is the author of Scriptorium (Beacon Press, 2016), selected for the National Poetry Series by Tracy K. Smith, and Horse and Rider (Texas Tech University Press, 2010). Of Scriptorium, poet Tracy K. Smith writes:
What may likely strike you on the first read is Range’s remarkable facility with form. She moves nimbly, naturally, with comfort and acrobatic delight through the rigors of sonnets, villanelles, anagrams, cento and the like. She submits joyfully to the whims of rhyme, allowing music to exert its will upon her train of mind, and she does so with such virtuosic ease that you may not even detect it on a first read. But what you will feel more than any of this, I am certain, is an urgent usefulness. These are poems for which form is not an end in itself.
Range has received awards and fellowships from the American Antiquarian Society, the National Endowment for the Arts, and the Rona Jaffe Foundation, among others. She currently teaches at Lawrence University and lives in Wisconsin
Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.

Modeling long-range dependent Gaussian processes with application in continuous-time financial models
Get PDFThis paper considers a class of nonstationary Gaussian processes with possible long-range dependence (LRD) and intermittency. The author proposes a new estimation method to simultaneously estimate both the LRD and intermittency parameter. An application of the proposed estimation method to a continuous-time financial model is discussed.continuous-time model; diffusion process; long-range dependent process; parameter estimation; stochastic volatility
Living with fire: protecting communities and restoring forests: findings and recommendations of the Front Range Fuels Treatment Partnership Roundtable
No full textMay-06.The Front Range Fuels Treatment Partnership Roundtable has worked together since 2004 to develop a long-term vision and roadmap for protecting communities from the risks of wildfire and restoring forest health in 10 Colorado Front Range counties (Boulder, Clear Creek, Douglas, El Paso, Gilpin, Grand, Jefferson, Larimer, Park and Teller). The results of the Roundtable's work show that the challenges posed by Front Range forests are significant. The Roundtable identified approximately 1.5 million forested acres along the Front Range that require treatment to protect communities or restore forest health, which the Roundtable refers to as fire risk mitigation and ecological restoration. At current treatment costs, achieving these goals could cost approximately 6 million currently available each year for forest treatments. This challenge falls on individual landowners as well as governmental land managers because a significant portion of acres that need treatment are on private land. While the challenge is daunting, the combined goals of reducing fire risk and restoring Front Range forests to good health are achievable. Success depends on leadership and action by federal, state, and local governments, as well as the proactive involvement of Front Range communities. The Roundtable has formulated a specific set of initiatives designed to provide additional resources for forest treatments, reduce treatment costs, drive local leadership and planning, and establish common priorities for forest treatments. Roundtable members will continue to work with federal, state, and local decision-makers to advance these initiatives and help catalyze the changes needed to protect and restore Colorado's forests. This report is a product of the Front Range Fuels Treatment Partnership Roundtable, a coalition of individuals from state and federal agencies, local governments, environmental and conservation organizations, the academic and scientific communities, and industry and user groups—all with a commitment to forest health and fire risk mitigation along Colorado's Front Range
Range Unit Root (RUR) Tests: Robust against Nonlinearities, Error Distributions, Structural Breaks and Outliers
Get PDFSince the seminal paper by Dickey and Fuller in 1979, unit-root tests have conditioned the standard approaches to analysing time series with strong serial dependence in mean behaviour, the focus being placed on the detection of eventual unit roots in an autoregressive model fitted to the series. In this paper, we propose a completely different method to test for the type of long-wave patterns observed not only in unit-root time series but also in series following more complex data-generating mechanisms. To this end, our testing device analyses the unit-root persistence exhibited by the data while imposing very few constraints on the generating mechanism. We call our device the range unit-root (RUR) test since it is constructed from the running ranges of the series from which we derive its limit distribution. These nonparametric statistics endow the test with a number of desirable properties, the invariance to monotonic transformations of the series and the robustness to the presence of important parameter shifts. Moreover, the RUR test outperforms the power of standard unit-root tests on near-unit-root stationary time series; it is invariant with respect to the innovations distribution and asymptotically immune to noise. An extension of the RUR test, called the forward?backward range unit-root (FB-RUR) improves the check in the presence of additive outliers. Finally, we illustrate the performances of both range tests and their discrepancies with the Dickey?Fuller unit-root test on exchange rate series.Publicad
