The stochastic nature of renewable energy sources (RESs) necessitates treating power system frequency response as a random process with a nonstationary probability density function (PDF). Based upon ...

Goldman Sachs raised the probability of a U.S. recession to 35%, up from 20%. Mark Zandi, chief economist at Moody's Analytics, talks with NPR's Michel Martin about the direction of the economy. For ...

A precise measurement of photometric redshifts (photo-z) is key for the success of modern photometric galaxy surveys. Machine learning (ML) methods show great promise in this context, but suffer from ...

Goldman Sachs has cut its probability forecast for a U.S. recession to 20% from 25%, shortly after raising it from 15%. After holding the odds at 15% for nearly a year, economists at Goldman — and ...

Abstract: It is known that the probability density function (PDF) of a continuous random variable is Fourier transform of the characteristic function (CF). In this paper, we propose a new type of PDF ...

What Is A Probability Density Function? A probability density function, also known as a bell curve, is a fundamental statistics concept, that describes the likelihood of a continuous random variable ...

ABSTRACT: Maximum entropy likelihood (MEEL) methods also known as exponential tilted empirical likelihood methods using constraints from model Laplace transforms (LT) are introduced in this paper. An ...
