Maximum entropy inversion of the diffraction data was done in order to obtain the variation in the spatial electron density distribution as a function of copper composition. These density maps show progressive positional and charge disorders in the V-O network induced by addition of copper. It is...
The problem is considered of estimating the parameters of regression models.We study the method of the adaptive estimation of the parameters of regression models with the use of the semiparametric approach to the estimation of the density distribution function of random errors. The accuracy of the ...

interpretation, probability distribution function can mean probability density function (in the context of continuous random variables) or probability mass function (in the context of discrete random variables). Therefore, it is recommended not to use probability distribution function since it may cause ...
where the integration is extended only over the coordinates q; this function is called the density matrix of the system. When x = x′, we have the function (7.3)ϱ(x,x)=∫|Ψ*(q,x)|2dq, which evidently determines the probability distribution for the coordinates of the system. Using...
{3})\)complexity become computationally dominant. However, the large prefactor in ERI evaluations with higher angular momenta functions and the spatial distribution of the basis functions obfuscate pinpointing such a crossing-point. For achieving an efficient Fock build with multi-GPUs, a concurrent ...
What Is a PDF vs. a CDF? A probability density function (PDF) explains which values are likely to appear in a data-generating process at any given time or for any given draw. A cumulative distribution function (CDF) instead depicts how these marginal probabilities add up, ultimately reaching...
In this case, the electron density distribution around the electrode corresponds to a Boltzmann distribution. The characteristic length of plasma for shielding, the Debye length, can be obtained from the exponent of the Boltzmann function: (1)eVkTe=L2nee2εkTe⇒L=εkTe/nee2=λDe, where ε ...
The Parzen-window method (also known as Parzen-Rosenblatt window method) is a widely used non-parametric approach to estimate a probability density functionp(x)for a specific pointp(x)from a samplep(xn)that doesn’t require any knowledge or assumption about the underlying distribution. ...
