When your device refuses to move past the estimation phase, it usually indicates a communication breakdown between the iPhone and Apple servers. This can be caused by network congestion or local ...

Before committing to a mortgage loan, you need to understand exactly what terms, conditions, costs, and rates you are agreeing to. Lenders provide this information with the standardized Loan Estimate ...

Covariance extension and spectral estimation form a foundational framework in the analysis and synthesis of stochastic processes. At its core, covariance extension refers to the problem of ...

Robotic lower-limb exoskeletons can augment human mobility, but current systems require extensive, context-specific considerations, limiting their real-world viability. Here, we present a unified ...

We consider autocovariance operators of a stationary stochastic process on a Polish space that is embedded into a reproducing kernel Hilbert space. We investigate how empirical estimates of these ...

In this talk, I will present a novel shape-constrained estimator of the autocovariance sequence resulting from a reversible Markov chain. A motivating application for studying this problem is the ...

Many scientific and economic applications involve the analysis of high-dimensional functional time series, which stands at the intersection between functional time series and high-dimensional ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

Abstract: The sample autocovariance function, estimated with mean lagged products of random observations, is the Fourier transform of the raw periodogram. Therefore, the quality of the sample ...
