Rate Distortion Function of Gaussian Asymptotically WSS Vector Processes

open access: yesEntropy, 2018
In this paper, we obtain an integral formula for the rate distortion function (RDF) of any Gaussian asymptotically wide sense stationary (AWSS) vector process.

Marginally specific alternatives to normal ARMA processes [PDF]

open access: yesProceedings of the 19th conference on Winter simulation - WSC '87, 1987
In many practical cases in time series analysis, marginal distributions in stationary situations are not Gaussian. It is therefore necessary to be able to generate and analyze non-Gaussian time series. Several non-Gaussian time series models are discussed in this paper.

Short‐Term Multi‐Horizon Line Loss Rate Forecasting of a Distribution Network Using Attention‐GCN‐LSTM

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Accurately predicting line loss rates is crucial for effective management in distribution networks, particularly for short‐term multihorizon forecasts ranging from 1 hour to 1 week. In this study, we propose attention‐GCN–LSTM, a novel method that integrates graph convolutional networks (GCN), long short‐term memory (LSTM) and a three‐level ...

Herbivore and mesocarnivore carcasses trigger divergent short‐term changes in soil properties

open access: yesJournal of Animal Ecology, EarlyView.
Scavengers reshape nutrient cycles in soils under carrion. Compared to herbivore carcasses, smaller but longer‐lasting carnivore remains boost nutrient levels and microbial activity in dry soils. Abstract Animal corpses act as pulses of organic matter (OM) and serve a key zoogeochemical role by providing localized nutrient inputs to soils and thereby ...

The Language of Gendered Violence and Sexual Aggression in the Spanish Civil War: Conceptualizations and Reassessments

open access: yesHistory, EarlyView.
Abstract This article examines the conceptual vocabulary through which violence against women during the Spanish Civil War has been interpreted, with particular attention to the longstanding predominance of the category ‘sexed violence’ (violencia sexuada).

An ecclesiastical court: Christian nationalism and perceptions of the US Supreme Court

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Recently, scholars have increasingly examined the unique blending of Christian and political ideology known as Christian nationalism. During this period, the US Supreme Court has increasingly ruled in ways that favor Christian nationalism, and Court watchers have criticized several justices for showing bias toward Christianity at best and ...

Minimum Mismatch Modeling (3M) Hyperparameter Selection in Autoregressive Moving Average (ARMA) Modeling

open access: yesIEEE Access
Hyperparameters of Autoregressive Moving Average (ARMA) modeling are the number of AR coefficients and the number of MA coefficients. The hyperparameter selection (HS) in ARMA modeling plays a critical role and can dominate the coefficient (parameter ...

A Comparative Review of Specification Tests for Diffusion Models

open access: yesInternational Statistical Review, EarlyView.
Summary Diffusion models play an essential role in modelling continuous‐time stochastic processes in the financial field. Therefore, several proposals have been developed in the last decades to test the specification of stochastic differential equations.

Functional Periodic ARMA Processes

open access: yes
Periodicity is a common feature in functional time series analysis. While autoregressive models in Hilbert spaces have been extended to incorporate it, existing approaches often remain loosely specified or fail to capture inter-seasonal dependencies. This paper introduces periodic autoregressive moving average (fpARMA) processes in general separable ...
