In this paper, we consider the problem of estimating multiple structural breaks in a long-memory FARIMA time series. The number of break points as well as their locations, the orders and the parameters of each regime are assumed to be unknown. A selection criterion based on the minimum description length (MDL) principle is proposed and a genetic algorithm is implemented for its optimization. Mo...
This article presents a novel long-memory wavelet model for approximating a stationary long-memory process. The proposed model is constructed in the wavelet domain in which the dependence structure is characterized by the variances of wavelet coefficients at different scales. This model can be easily incorporated into more complex model structures such as a generalized linear model. For inferen...
Recent projections of global sea-level rise by 2100 C.E. range from 20 cm (Meehl et al., 2007) to as much as 2 m (Vermeer and Rahmsdorf, 2009; Pfeffer et al., 2008), and sea level is projected to rise in the coming centuries even further. Without adaptation, a rise by 0.5 m would displace 3.8 million people in the most fertile part of the Nile River Delta (FitzGerald et al., 2008). A rise by 2 ...
After recreational exposure to river water in Uganda, 12 (17%) of 69 persons had evidence of schistosome infection. Eighteen percent self-medicated with praziquantel prophylaxis immediately after exposure, which was not appropriate. Travelers to schistosomiasis-endemic areas should consult a travel medicine physician.
