    Time series aggregation, disaggregation and long memory by Dmitrij Celov, Remigijus Leipus

    Published 2023-09-01
    “… Large-scale aggregation and its inverse, disaggregation, problems are important in many fields of studies like macroeconomics, astronomy, hydrology and sociology. It was shown in Granger (1980) that a certain aggregation of random coefficient AR(1) models can lead to long memory output. …”

    Comparison of the results obtained by Iman transform with Laplace transform by NIHAL OZDOGAN

    Published 2024-12-01
    “…However, integral transform methods can give consistent solutions to many complex problems and have many application areas such as physics, mechanics, engineering, astronomy. In this work, two integral transforms, Iman transform and the well-known Laplace transform were studied comparatively to facilitate the solution of linear ordinary differential equations with constant coefficients. …”
