Sentences with phrase «of stochastic variation»

However, both these cases consider the ability of stochastic variation to drive the formation of a single stable attractor.

That requires a model of the stochastic variations in the data and a precise definition of, what the trend means in the particular consideration.

Time variation of the stochastic discount tells us to expect low returns on equity during good economic times.

«Stochastic variations of migration speed between cells in clonal populations.»

It amazes me that so much of the natural variation we observe within and across species is due simply to stochastic processes in the population.

We found much higher variance in RND values for intronic fragments consisting of a reduced number of sites, likely due to stochastic variation in the mutation process.

None of the random permutations exceeded the observed differentiation (P < 0.001), indicating that these regions of differentiation are unlikely to reflect simple stochastic variation in differentiation across the genome due to the reduced number of individuals sampled.

It produces a much more detailed view of the state of nuclear DNA inside a cell population, showing the enormous variations in stochastic mutational damage that takes place over the years.

Broadly speaking, however, analysis of transcriptional regulation at the single cell level has provided evidence for a strong stochastic element: genetically identical cells within the same environment show significant variation in molecular phenotype, in a fluctuating manner [24].

tpinlb, climate models don't «predict» year - specific phenomena arising from stochastic variation that adds «noise» to progression of climate states under the influence of persistent forcings.

However, stochastic weather variations will lead to differing amounts of cooling for synoptically distinct regions.

• There is strong evidence that the multidecadal SAT variability in the Atlantic (and globally) is driven (at least partly) by variations in the MOC • A stochastic scenario is most plausible, in which the ocean is driven by the low - frequency portion of the atmospheric variability (NAO).

I propose the following Climatic null hypothesis that: «Natural climatic variation is quantified by the stochastic uncertainty envelope of historical and paleo data, embodying the nonlinear chaotic interaction of atmospheric, oceanic, volcanic, solar, and galactic processes, including climate persistence quantified by Hurst - Kolmogorov dynamics.»

«Natural climatic variation is quantified by the stochastic uncertainty envelope of historical and paleo data, embodying the nonlinear chaotic interaction of atmospheric, oceanic, volcanic, solar, and galactic processes, including climate persistence quantified by Hurst - Kolmogorov dynamics.»

We investigate three methods for simultaneous estimation of the Hurst parameter (H) and the standard deviation (σ) for a Hurst - Kolmogorov stochastic process, namely the maximum likelihood method and two methods based on the variation of the standard deviation or of the variance with time scale.

Nevertheless, the salutary aspect of the GISP 2 data is the clear indication it provides of a gentle, truly secular cooling trend since the Holocene optimum, overlain by weakly stationary, strongly structured, quasi-Gaussian stochastic variations whose ordinate distribution and power - spectrum both diverge from anything resembling a Poisson process of abrupt jumps.

Although it is clear that further attention is required in defining and characterizing the aspects of this variation (e.g. frequency and amplitude [44,65]-RRB- that lead to differences in species responses, a more immediate empirical challenge is to characterize and separate the effects of periodic, stochastic and / or cyclical natural variations [61] from directional change imposed by long - term climatic forcing.

But once you look at the rate of change you start to realise that it's not just random noise or «stochastic» variation.

There's a stochastic component to «energy in» due to variation in solar output, wobble, orbital asymmetry, albedo and a whole host of other factors (even small things like kinetic energy that is transferred from meteorites and space dust that is constantly hitting the earth).
