摘要

摘要本文旨在分析波兰第二波COVID-19大流行期间住院人数、重症监护患者人数、COVID-19检测阳性人数、死亡人数和康复人数的函数数据。为此，作者首先将 16 个省的数据转换为平滑函数，然后使用主成分分析和多重函数对函数线性回归模型来预测第二波大流行期间因感染 COVID-19 而住院和重症监护的病人数量。最后，将结果与之前在波兰 COVID-19 大流行第二波和第三波合并数据中获得的结果进行了比较（Hęćka，2023 年）。

The Second Wave of the COVID-19 Pandemic in Poland – Characterised Using FDA Methods

Abstract The aim of this article was to analyse functional data of the number of hospitalised individuals, intensive care patients, positive COVID-19 tests, deaths and convalescents during the second wave of the COVID-19 pandemic in Poland. For this purpose, firstly the author convert data of sixteen voivodeships to smooth functions, and then used the principal component analysis and multiple function-on-function linear regression model to predict the number of hospitalised and intensive care patients due to the COVID-19 infection during the second wave of the pandemic. Finally, the results were compared with those previously obtained for the combined data of the second and third wave of the COVID-19 pandemic in Poland (Hęćka, 2023).
