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 ...
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 ...
We use the cross-section regression approach of Fama and MacBeth (1973) to construct cross-section factors corresponding to the time-series factors of Fama and French (2015). Time-series models that use only cross-section factors provide better descriptions of average returns than time-series mode...

repeated cross-sectional regression 重复截面回归(Repeated Cross-sectional Regression)是一种常用的统计分析方法,主要用于研究随时间变化的现象。这种方法结合了截面数据和时间序列数据的优点,能够更全面地揭示变量之间的关系。 在重复截面回归中,研究者收集不同时间点上的截面数据,并对这些数据进行回归分析。通过这种方式...
