K\"ahlerian information geometry for signal processing
, 2015 We prove the correspondence between the information geometry of a signal filter and a K\"ahler manifold. The information geometry of a minimum-phase linear system with a finite complex cepstrum norm is a K\"ahler manifold.

Journal of Fish Biology, EarlyView.Abstract A new species of Characidium is described from the Urubamba River basin, within the Ucayali‐Urubamba Piedmont ecoregion, Peru. The new species can be readily distinguished from all congeners, except Characidium cacah, Characidium chicoi, Characidium helmeri, Characidium mirim, Characidium nana, Characidium nupelia, Characidium sterbai ...

Journal of Intellectual Disability Research, EarlyView.ABSTRACT Over time, sexuality has become a crucial aspect in people's lives, regardless of physical, intellectual or social conditions, ranging from sex and sexually transmitted diseases to gender identity and sexual orientation. The aim of this study was to carry out a review of the scientific literature on sexual orientation in people with ...

Weak convergence of the sequential empirical processes of residuals in ARMA models [PDF]
This paper studies the weak convergence of the sequential empirical process $\hat{K}_n$ of the estimated residuals in ARMA(p,q) models when the errors are independent and identically distributed.

Journal of Management Studies, EarlyView.Abstract Humanity – the virtue enabling meaningful human connection – is vital to the leadership we need to survive our polycrisis context. As a prerequisite to sustainable human community, the virtue of humanity is considered universal. It has been claimed as a ‘higher‐order virtue’, comprised of and enacted by – but irreducible to – a suite of ‘lower‐

TEMPORAL AGGREGATION EFFECTS IN CHOOSING THE OPTIMAL LAG ORDER IN STABLE ARMA MODELS. SOME MONTE CARLO RESULTS. [PDF]
A crucial aspect of empirical research based on ARIMA(p,q) model is the choice of the appropriate lag order. Several criteria have been used in order to identify the appropriate order of a ARIMA(p,q) process.

When and Where: Predicting Human Movements Based on Social Spatial-Temporal Events
, 2014 Predicting both the time and the location of human movements is valuable but challenging for a variety of applications. To address this problem, we propose an approach considering both the periodicity and the sociality of human movements. We first define

On the parameter estimation of ARMA(p,q) model by approximate Bayesian computation
, 2019 In this paper, the parameter estimation of ARMA(p,q) model is given by approximate Bayesian computation algorithm. In order to improve the sampling efficiency of the algorithm, approximate Bayesian computation should select as many statistics as possible with parameter information in low dimension. Firstly, we use the autocorrelation coefficient of the
