Time-series Regression: 时序回归 Cross-sectional Regression: 截面回归 风险分解公式:因子风险模型背景 在因子风险模型中,投资组合的风险可以通过以下公式进行分解: 总风险分解 给定R 为投资组合收益, B 为因子暴露矩阵, f 为因子收益, ϵ 为特异收益,我们有: R=Bf+ϵ 投资组合的方差(总风险)可表示为: ...

Panel regression specifically analyses cross sectional time series data and incorporates these effects into the model. It also increases the sample size, which may be a trivial benefit while panel models (especiallyfixed effects) can control for unobserved heterogeneity which may be crucial. The ...
Section 3 conducts portfolio analyses and cross-sectional regression tests to determine whether aggregate volatility risk is priced in the whole bond universe and in each rating category. Section 4 examines the role of the idiosyncratic volatilities of bonds and stocks in the cross-section of ...
The power of panel regression is in using both cross section and time series observations accounting for both cross sectional and time series effects. The following shows a common problem in retail: same store sales solved by taking into account differencesin stores and differences in time series ...
