On the Role of Seasonal Intercepts in Seasonal Cointegration [PDF]
Oxford Bulletin of Economics and Statistics, 1999 In the paper we consider the role of seasonal intercepts in seasonal cointegration analysis. For the nonseasonal unit root, such intercepts can generate a stochastic trend with a drift common to all observations. For the seasonal unit roots, however, we show that unrestricted seasonal intercepts generate trends that are different across the seasons ...

Light-harvesting chlorophyll a/b-binding protein-coding genes in jatropha and the comparison with castor, cassava and arabidopsis [PDF]
PeerJ, 2020 The Lhc (light-harvesting chlorophyll a/b-binding protein) superfamily represents a class of antennae proteins that play indispensable roles in capture of solar energy as well as photoprotection under stress conditions.

The Journal of nutrition, health and aging, 2020 Frailty in older adults is a complex condition in which only a minor external stressor may cause severe complications leading to death. In the context of the recent devastating bushfires in Australia and the worldwide COVID-19 pandemic, recognising and protecting those affected has magnified the impact and public health importance of frailty.

Seasonal integration and the evolving seasonals model
International Journal of Forecasting, 1997 Abstract The paper uses a model of seasonality popular in the 1960s, the evolving seasonals model, to explore issues relating to testing for unit roots in seasonal time series. The model is used to show how data can be transformed in such a way that tests for seasonal integration simply become those for regular unit roots.
