Data on copula modeling of mixed discrete and continuous neural time series
Data in Brief, 2016 Copula is an important tool for modeling neural dependence. Recent work on copula has been expanded to jointly model mixed time series in neuroscience (“Hu et al., 2016, Joint Analysis of Spikes and Local Field Potentials using Copula” [1]).

Improving Upon the Marginal Empirical Distribution Functions when the Copula is Known [PDF]
At the heart of the copula methodology in statistics is the idea of separating marginal distributions from the dependence structure. However, as shown in this paper, this separation is not to be taken for granted: in the model where the copula is known ...

Journal of Forecasting, EarlyView.ABSTRACT Using online job advertisement data improves the timeliness and granularity depth of analysis in the labor market in domains not covered by official data. Specifically, its variation over time may be used as an anticipator of official employment variations.

Don't You Know That You're Toxic? How Influencer‐Driven Misinformation Fuels Online Toxicity
Psychology &Marketing, EarlyView.ABSTRACT Research on misinformation has focused on message content and cognitive bias, overlooking how source type shapes toxic engagement. This study addresses that gap by showing that influencer‐driven misinformation does not merely increase toxicity: it reconfigures its nature and persistence through relational and social influence mechanisms ...

To be or not to be? About the copula system in Buli (Gur) [PDF]
, 2008 This talk concerns the copula system in Buli, a Ghanaian language which has also been attested in Bahia (Rodrigues 1935, Zwernemann 1968). Special focus will be put on the categorization of two copula-reminiscent elements for which I will propose a ...

Managerial and Decision Economics, EarlyView.ABSTRACT Exchanges in franchise systems are embedded in the level of trust that exists in franchisee–franchisor relationships. Although trust is essential in business relationships, it can unfold a negative side effect on the appreciation of exchange in these relationships as hidden costs of trust.

Estimating Risk of Natural Gas Portfolios by Using GARCH-EVT-Copula Model
The Scientific World Journal, 2015 This paper concentrates on estimating the risk of Title Transfer Facility (TTF) Hub natural gas portfolios by using the GARCH-EVT-copula model. We first use the univariate ARMA-GARCH model to model each natural gas return series.

Mathematical Methods in the Applied Sciences, EarlyView.We develop a full randomization of the classical hyper‐logistic growth model by obtaining closed‐form expressions for relevant quantities of interest, such as the first probability density function of its solution, the time until a given fixed population is reached, and the population at the inflection point.
