在经济学和社会科学的研究中,评估政策或干预措施的影响至关重要。传统的评估方法往往面临着选择偏差和反事实问题,难以准确测量政策的实际效果。**广义合成控制(Generalized Synthetic Control)**作为一种创新的评估技术,提供了一种系统化的方法来解决这些问题。本文将探讨广义合成控制的基本概念、方法、应用场景及其优势与...
Generalized synthetic control method: Causal inference with interactive fixed effects models. Political Analysis, 25(1), 5776.Yiqing Xu. Generalized synthetic control method: Causal inference with interactive fixed effects models. Political Analysis, 25(1):57-76, 2017....
This method has several advantages. First, it allows the treatment to be correlated with unobserved unit and time heterogeneities under reasonable modeling assumptions. Second, it generalizes the synthetic control method to the case of multiple treated units and variable treatment periods, and improves ...
gsynthimplements thegeneralized synthetic control method, which imputes counterfactuals for each treated unit using control group information based on a linear interactive fixed effects model. This version supports unbalanced panels and implements the matrix completion method. ...
We applied a two-stage generalized synthetic control method to compare health outcomes in exposed (from 8 November to 5 December 2018) versus unexposed counties and used random-effects meta-regression to evaluate the effect modification of county-level socioeconomic variables on the observed health ...
Dependence of Saline-Induced Natriuresis upon Exposure of the Kidney to the Physical Effects of Extracellular Fluid Volume Expansion In many previous studies, the natriuresis induced by saline loading has been demonstrated to persist even though glomerular filtration rate (GFR) has been ...

The applications ofsynthetic divisions of ascending and reducing power in linear control system 升幂与降幂综合除法在线性控制系统中的应用 3. To give a general method on how to find the similitude transformation matrix—matrixsynthetic division.
In this section, a direct performance optimization control method is proposed with a dual-rotor turbofan engine as the controlled plant whose schematic diagram has been shown in Fig. 5. The main components of the turbofan engine include an inlet, a fan, a compressor, a combustion chamber, a ...
Finally, we also present a new layer that can be attached to any deep learning model designed for unsupervised anomaly detection to transform it into an active anomaly detection method, presenting results on both synthetic and real anomaly detection datasets. 展开 ...
1. ADASYN is a method that generates synthetic samples for the minority class, thereby achieving a more balanced distribution of data points among the different classes. This approach is beneficial because imbalanced data can hinder the performance of supervised ML algorithms, which often prioritize ...
