面板数据分析（Panel Data Analysis）是一种统计分析方法，用于分析在多个时间点上收集的数据。这种数据也被称为纵向数据（Longitudinal Data）或追踪数据（Cross-sectional Time-series Data），因为它包含了多个个体（如人、公司、国家等）在不同时间点的观测值。一、主要特点 1. 多个时间点：数据收集跨越多个时间点...
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 ...
“cross-sectional” component • Information about cases over time – A „longitudinal‟ or „time series‟ component • Panel datasets are described in terms of: • N, the number of individual cases • T, the number of waves – If N is “large” compared to T, the dataset...

面板数据模型用于分析面板数据中各自变量X对因变量Y的影响。 常见的数据形式有时间序列数据(Time series data),截面数据(Cross-sectional data)和面板数据(Panel data)。从维度来看,时间序列数据和截面数据均为一维。面板数据可以看做为时间序列与截面混合数据,是截面上个体在不同时点重复观测数据,因此它是二维数据。
A Panel Data Model refers to a statistical model used in social sciences that incorporates both cross-sectional and time-series data. It is divided into four categories: static, dynamic, stable, and nonstable panel data models. This model helps analyze and understand the long-term relationship ...
tsset panelvar timevar declares the data to be panel data, also known as cross-sectional time-series data, which contain one time series for each value of panelvar. This allows you to also analyze your data with the xt commands without having to xtset your data. tsset without arguments ...
time series dependenceWe provide various norm-based definitions of different types of cross-sectional dependence and the relations between them. These definitions facilitate to comprehend and to characterize the various forms of cross-sectional dependence, such as strong, semi-strong, and weak dependence...
Using panel data with large cross section (n) and time series dimensions (T), the estimators are based on the long-run average variance estimate using bandwidth equal to T. The new estimators include the panel pooled least squares estimators and the limiting cross sectional least squares ...
