    Improvement of the Nonparametric Estimation of Functional Stationary Time Series Using Yeo-Johnson Transformation with Application to Temperature Curves by Sameera Abdulsalam Othman, Haithem Taha Mohammed Ali

    Published 2021-01-01
    “…An application algorithm was proposed to transform the positive original responses using the first model and the stationary responses using the second model to improve the nonparametric estimation of the functional time series. The Box-Cox model contributed to improving the results of the nonparametric estimation of the original data, but the results become somewhat confusing after attempting to make the transformed response variable stationary in the mean, while the functional time series predictions were more accurate using the transformed stationary datasets using the Yeo-Johnson model.…”

    Estimating the contribution of Arctic sea-ice loss to central Asia temperature anomalies: the case of winter 2020/2021 by Lara R Cosford, Rohit Ghosh, Marlene Kretschmer, Clare Oatley, Theodore G Shepherd

    Published 2025-01-01
    “…In particular, we find that Central Asia’s 2021 negative winter surface air temperature anomaly (relative to 1980–2020) can be fully explained by the BKS-ice anomaly. We further estimate that BKS-ice loss has more than halved the winter warming over Central Asia over the past 40 years. …”
