The Dance of the Long-tailed Manakin
Charles Darwin is famous for his contributions to evolution and natural selection. He developed the theory of natural selection and further realized that there are many forms of natural selection. One of these forms is called sexual selection, which he describes in one of his famous books, The Descent of Man, and Selection in Relation to Sex. The idea rose from the observation that some organis...
متن کاملOn the relevance of long-tailed durations
In this paper we obtain large deviation bounds for the queue length in a buffer fed by an M=G=1 process with G long-tailed, and in the limit that the arrival intensity grow to infinity along with the service rate so as to keep the offered load constant. This provides an example in which long-tailed arrival distributions are no bar to obtaining statistical multiplexing gain when such arrivals ar...
متن کاملVisualizing bivariate long-tailed data
Variables in large data sets in biology or e-commerce often have a head, made up of very frequent values and a long tail of ever rarer values. Models such as the Zipf or Zipf–Mandelbrot provide a good description. The problem we address here is the visualization of two such long-tailed variables, as one might see in a bivariate Zipf context. We introduce a copula plot to display the joint behav...
متن کاملConvolutions of long-tailed and subexponential distributions
We study convolutions of long-tailed and subexponential distributions (probability measures), and more general finite measures, on the real line. Our aim is to prove some important new results, and to do so through a simple, coherent and systematic approach. It turns out that all the standard properties of such convolutions are then obtained as easy consequences of these results. Thus we also h...
متن کاملDistribution of the Long-tailed Weasel (Mustela frenata) in Illinois
Knowing the geographic distribution of any species is an important first step toward understanding its ecology. Long-tailed weasels (Mustela frenata) are secretive and difficult to detect, so little is known about their distribution in Illinois. To fill this gap in the knowledge, we solicited information from museum curators about the sites where long-tailed weasel specimens were collected in I...
