Weighted average formula Let's repeat what the weighted average formula looks like: xˉ=w1x1+w2x2+…+wnxnw1+w2+…+wnxˉ=w1+w2+…+wnw1x1+w2x2+…+wnxn But what does it mean? To figure out how to calculate a weighted average, we need to know the weight of each value. Typically, ...
However, the supports of the averages are constrained by the size, geometry, and orientation of the original supports. Essentially, the larger supports must be constructed to encompass perfectly the smaller original supports. This hierarchical system is commonly used for reporting census data. For ...
Average Geodesic DistanceSelf-Similar MeasureThe average geodesic distance is an important index in the study of complex networks. In this paper, we investigate the weighted average distance of Pentadendrite fractal and Pentadendrite networks. To provide the formula, we use the integral of geodesic ...
we study this matrixC_2in more detail. Notice that this constraint (2) onC_2is overdetermined, oncep > N. Therefore, the condition (2) onC_2can only be imposed in the largeNlimit. The Gaussian average of a functionf(A,B) is defined by ...
This variance is a function of , the average of the reciprocal weights; if the weights are scaled arbitrarily, then so is this variance. We can also fit this model by typing . regress y x1 x2 [aweight=1/a] This input will produce the same estimates of the coefficients and covariance ...

The MCS method carries out N times uniform sampling of X on [0,1]n, and takes the average value of N times sampling results as the integral problem in an empirical approximation to the estimation of Eq. (2):(3)Pf¯=1N∑i=1Nf(Xi)≈Pf Through the Strong Law of Large Numbers (...

Average Fermat DistanceFinite PatternIn this paper, we investigate a class of self-similar networks modeled on a self-similar fractal tree, and use the self-similar measure and the method of finite pattern to obtain the asymptotic formula of node-weighted average Fermat distances on fractal tree ...
In this paper, we develop the multifractal detrending weighted average algorithm of historical volatility (MF-DHV) for one-dimensional multifractal measure based on the classical multifractal detrended fluctuation analysis (MF-DFA). In the calculation process of getting a local trend for MF-DHV, ...
