Visualizing bivariate longtailed data
, 2010
"... Variables in large data sets in biology or ecommerce often have a head, made up of very frequent values and a long tail of ever rarer values. Models such as the Zipf or ZipfMandelbrot provide a good description. The problem we address here is the visualization of two such longtailed variables, as ..."

Waitingtime tail probabilities in queues with longtail servicetime distributions
 QUEUEING SYSTEMS
, 1994
"... We consider the standard GI/G/1 queue with unlimited waiting room and the firstin firstout service discipline. We investigate the steadystate waitingtime tail probabilities P(W> x) when the servicetime distribution has a longtail distribution, i.e., when the servicetime distribution fails ..."

approximations with these longtail servicetime distributions can be remarkably inaccurate for typical x values of interest. We also derive multiterm asymptotic expansions for the waitingtime tail probabilities in the M/G/1 queue. Even three terms of this expansion can be remarkably inaccurate for typical x

pRB, the product of the retinoblastoma tumor suppressor gene, operates in the midst of the cell cycle clock apparatus. Its main role is to act as a signal transducer connecting the cell cycle clock with the transcriptional machinery. In this role, pRB allows the clock to control the expression of banks of genes that mediate advance of the cell through a critical phase of its growth cycle. Loss of pRB function deprives the clock and thus the cell of an important mechanism for braking cell proliferation through modulation of gene expression. pRB and the G1 Restriction Point pRB exerts most and perhaps all of its effects in a defined window of time in the first two thirds of the G1 phase of the cell cycle. As demonstrated by Pardee almost two decades ago, this is the time window during which the mam
When the Error Distribution is LongTailed Symmetric
"... and weighted Theil’s (Weighted Theil) estimators are compared under the simple linear regression model in terms of their bias and efficiency when the distribution of error terms is longtailed symmetric. Key words: Longtailed symmetric, ordinary least squares, modified maximum likelihood, least abs ..."

, 2001
"... We have analyzed DNA sequences of known genes from 16 yeast chromosomes (Saccharomyces cerevisiae) in terms of oligonucleotides. We have noticed that the relative abundances of oligonucleotide usage in the genome follow a longtail Lévylike distribution. We have observed that long genes often use s ..."

LongTail Learning: A Unique Opportunity for CSCL?

Wired magazine article to describe how our culture and economy is increasingly shifting away from a focus on a relatively small number of “hits ” (mainstream products and markets) at the head of the demand curve toward a huge number of niches in the tail (as exemplified by companies such as Amazon o ..."

Longtail learning refers at least to two aspects: (1) learning about exotic topics outside the mainstream
Capturing longtail distributions of object subcategories
"... We argue that object subcategories follow a longtail distribution: a few subcategories are common, while many are rare. We describe distributed algorithms for learning largemixture models that capture longtail distributions, which are hard to model with current approaches. We introduce a general ..."

Shelf space strategy in longtail markets

"... The Internet is known to have had a powerful impact on online retailer strategies in markets characterised by longtail distribution of sales [1]. Such retailers can exploit the long tail of the market, since they are effectively without physical limit on the number of choices on offer. Here we exa ..."
