Key Determinants Of Life Satisfaction In Older Adults, Barry Nuqoba, Yi Wen Tan, Yen Cong Wong, Wensi Lim
ROSA Research Briefs
Life satisfaction constitutes a fundamental facet of wellbeing, exerting an influence on an individual's mental and emotional state (Zissi & Barry, 2006). Among older adults, elevated levels of life satisfaction are frequently linked to a more optimistic outlook, contributing to improved health and resilience (Khodabakhsh, 2022; Zheng, Huang, & Fu, 2020). This in turn enhances societal involvement, both in the professional and social domains (Khodabakhsh, 2022). It is also vital to acknowledge that life satisfaction is a multifaceted construct, intricately influenced by an array of external and internal determinants. Life satisfaction is essentially a subjective judgement and assessment of one’s …
Multivariate Stochastic Volatility Models: Bayesian Estimation And Model Comparison, Jun Yu, Renate Meyer
Multivariate Stochastic Volatility Models: Bayesian Estimation And Model Comparison, Jun Yu, Renate Meyer
Research Collection School Of Economics
In this paper we show that fully likelihood-based estimation and comparison of multivariate stochastic volatility (SV) models can be easily performed via a freely available Bayesian software called WinBUGS. Moreover, we introduce to the literature several new specifications that are natural extensions to certain existing models, one of which allows for time-varying correlation coefficients. Ideas are illustrated by fitting, to a bivariate time series data of weekly exchange rates, nine multivariate SV models, including the specifications with Granger causality in volatility, time-varying correlations, heavy-tailed error distributions, additive factor structure, and multiplicative factor structure. Empirical results suggest that the best specifications …
