近日，中国科学院分子细胞科学卓越创新中心（生物化学与细胞生物学研究所）陈剑峰研究组，林昶东（第十批会员）副研究员等研究发现抗生素头孢他啶 (ceftazidime) 能够在体外通过结合新冠病毒 (SARS-CoV-2) 刺突蛋白 (S蛋白) 并阻断其与人血管紧张素转换酶2 (Angiotensin converting enzyme 2, ACE2) 的相互作用，从而有效地抑制新型冠状病毒感染宿主...
Floating tar balls are a product of weathering of crude oil in the marine environment. They have been found to be prevalent in the world ocean, particularly in the 1960s and 1970s before stricter cont...
ARMA模型和TAR模型在貂年捕获量中的预测结果比较
时间序列 门限自回归 ARMA模型 平均误差率
2011/11/12
【目的】 对ARMA模型和门限自回归模型在貂年捕获量的预测结果进行比较。【方法】 利用我国1848年至1909年貂年捕获量数据，分别建立ARMA模型和门限自回归模型，拟合后对未来五年的年捕获量进行预测，比较2个模型的拟合和预测效果。【结果】 ARMA模型和门限自回归模型的平均误差率(MER)分别为27.93％、3.2％。【结论】 门限自回归模型对于处理循环的数据具有明显的预测优势，预测效果优于AR...
