Cross Section 界面介绍 PCB设计软件allegro提供了一个集成、方便、强大的层叠设计与阻抗计算控制的工具,叫做Cross Section。如图所示,可以非常直观地进行材料选择,参数确定,然后得到最终阻抗结果。 其中,各项选项的含义如下: Subclass Name:各布...
Crosssection密封圈是一种用于防止液体或气体泄漏的机械部件,其横截面形状和尺寸对于选择合适的密封圈或进行相关的设计计算至关重要。在选择密封圈时,需要根据具体的应用场景和密封要求选择合适的横截面形状和尺寸,并考虑密封圈的材料、...
一旦知道了\beta(c),也就同时得到了因子收益率: F_{t+1}=\left(\beta_t^{\prime}\beta_t\right)^{-1}\beta_t^{\prime}R_{t+1}^e 在这个研究框架下,Kelly, Pruitt and Su (2019) 和 Gu, Kelly and Xiu (2021) 分别提出了 IPCA(工具变量 PCA)和 autoencoder 算法。前者视\beta为 firm cha...
