You are collecting an individual's data over time.
This is different than time-series as you are looking at a stream of data. This means that to have a panel data you must contact that same person over a number of years and have them fill out the same survey to get the information as it changes over time. This makes the issues we discuss here particularly important to researchers using TSCS data. In addition, TSCS data, used mainly in political science, often contains more slowly changing, historically determined variables (such as GDP per capita), and researchers using it are often more interested in specific effects in specific higher-level entities. <-ġ The difference between TSCS and panel data lies partly in its sample structure: TSCS data has comparatively few higher-level entities (usually groups of individuals such as countries, rather than individuals) and comparatively many measurement occasions (Beck and Katz 1995). The European Social Survey is time series cross sectional, surveying European populations, but anonymously every two years, also quite well-used.īoth types have different bias concerns, for example the way they exit from the sample, or attrition.ĮDIT: THIS IS INCORRECT->Couldn't view the whole article, but it looks like given they are investigating properties of FEVD and also state the benefits of FEVD procedure in the first sentence of the introduction as dealing with panel data, they're using panel data. To give you two examples, the US health data NHIS, a panel data, is quite famous because it's 50 years of the (more/less the same, though they built up on it) survey on the same households, following up every iteration. Same amount of data, but different storytelling from the data. You gather data on 100 children the next year, but could be on different children. Time series cross sectional: you gathered data on 100 children.
You do the same thing on 100 other children at the same time.
You follow and keep track of the same child's growth over 10 years. Panel: you start gathering data on a child. The main difference is whether you're following up with your subject/data or not.
