The quantities which are involved do not necessarily occur more than once but since some may be considered more important than others they are 'weighted' by a number which is comparable to a frequency.doi:10.1007/978-1-349-03146-7_12Arthur H. HallMacmillan Education UK...
These weighted spaces of vector-valued functions have attracted a great deal of attention recently (see, e.g., [22, 23, 27, 29, 30]) partly due to the fact that the setup generates a number interesting mathematical questions related to vector valued functions that is naturally connected to...
One of the big questions in science, and particularly important for the comprehension of complex systems, is to understand which are the scales relevant to a given phenomenon and how these scales are interrelated. The geometric renormalization of complex networks provides a powerful framework to disen...
However, hardly any studies have tested the sensitivity of this crisis index to the various possible choices of “anchor” currencies. A few questions emerge naturally when we want to construct the EMP index and employ the index for evaluating the incidences of speculative attacks against the ...

In DNA microarray experiments, measurements from different biological samples are often assumed to be independent and to have identical variance. For many datasets these assumptions have been shown to be invalid and typically lead to too optimistic p-val

To address the three major research questions, we consider three sets of experiments. In the first set of experiments, we study whether the target weighted networks in two different domains show any fractal or multi-fractal scaling behaviors. Towards this goal, we applied the proposed FBCw to ...
So I went back and looked at the numbers to see what an equal-weighted portfolio of these 10 S&P 500 sector ETFs would have looked like. From the beginning of 2004 through June 30 of this year the S&P 500 was up 7.7% per year. An equal-weighted portfolio of the sector ETFs rebalanced...
Monthly chain-weighted CPI numbers are updated and revised retroactively each month, with a final index number published 12 months after the fact. This makes it less useful as a real-time indicator of the cost of living. Regular CPI is considered to be the final estimate for each month that...
