IPCA: Instrumented Principal Component Analysis 理论部分 或者这里: 张楚珩:【Paper】深度资产定价模型 上述形式有几个要点: 1、工具变量 \mathbf{Z} 时变,一般选择为基金的显式Characteristics。如果显式的Characteristics为 P 维,那么时不变的 \mathbf{\Gamma}_{P\times K} 本质上就是个特征(因子)选择矩阵,线...
ALS方法能够处理不平衡面板数据，提供稳定估计结果，同时考虑了数据的正常化条件，确保估计的唯一性。这一方法详细阐述于Bryan Kelly在2020年发表的《Instrumented Principal Component Analysis》一文中。

As previously noted, the cell may constitute a temporary gaging replacement for a normally used anchor pin of identical essential working dimensions, or may if desired be itself employed as a permanent working component. For the subsequent analysis of the angular direction of force application, the...
principal component analysis and partial least squares regression, can be used to identify important influencing factors, and 2) propose a framework for predicting the failure rates based on the reported failures. The framework is illustrated with a case study based on the data collected from the ...
Following data augmentation and principal component analysis (PCA), the MLP+PCA model achieved an accuracy of 0.9, a precision of 0.92, a recall of 0.9, and an F1 score of 0.91. This underscores the efficacy of the approach for LS assessment. This study lays the foundation for the future ...

inverse analysisresidual stress tensorThe residual stress tensor near the surface of a metal structural component or products of metallurgical processes (particularly welding) is considered in view of the estimation of its governing components. These are: the two principal stresses if the directions are...
The objectives are twofold: (1) to assess the safety of the modified humeral component under peak anticipated loads in fatigue, and (2) verify the strains measured under physiological loads with strains modelled using finite element analysis (FEA). Four modified titanium alloy humeral components ...
