求助：Repeated cross sections重复截面数据和面板数据的区别？

A data structure in which the same (cross-sectional) units are observed over two or more periods is called a panel data and contains more information than a repeated cross-section.

Examples of repeated cross-sections (RCS) include daily tracking polls of political opinions during campaigns, monthly Current Population Surveys of unemployment, yearly national health interview surveys, and quadrennial election studies of presidential voting. Each iteration is a distinct sample, as opposed to panels in which the same people are interviewed two or more times. By asking the same questions on repeated survey samples from the same population, RCS studies allow us to track trends and to establish causal inferences. One analytic challenge is to maintain both the representativeness and the comparability of samples as fieldwork methods or sources change.

Cross-sectional survey data are data for a single point in time. Repeated cross-sectional dataare created where a survey is administered to a new sample of interviewees at successive time points. For an annual survey, this means that respondents in one year will be differentpeople to those in a prior year. Such data can either be analysed cross-sectionally, by looking at one survey year, or combined for analysis over time. See Section three for examples of analyses of repeated cross-sectional data.

每个时间截面上的个体都不一样，称为重复截面数据。具体案例看看附件中截图
