Panel Data Panel data is obtained by observing the same person, firm, county, etc over several periods. Unlike the pooled cross sections, the observations for the same cross section unit (panel, entity, cluster) in general are dependent. Thus cluster-robust statistics that account for correlation within panel should be used.


Details. This Durbin–Watson test uses the auxiliary model on (quasi-)demeaned data taken from a model of class plm which may be a pooling (the default), random or within model. It performs a Durbin–Watson test (using dwtest from package lmtest on the residuals of the (quasi-)demeaned model, which should be serially uncorrelated under the null of no serial correlation in idiosyncratic errors.

Panel data refers to data that follows a cross section over time—for example, a sample of individuals surveyed repeatedly for a number of years or data for all 50 states for all Census years. • reshape There are many ways to organize panel data.

Autokorrelation paneldata

Panel data allows you to control for variables you cannot observe or measure like cultural factors or difference in business practices across companies; or variables that change over time but not across entities (i.e. national policies, federal regulations, international agreements, etc.). This is, it accounts for individual heterogeneity.

The auto part of autocorrelation is from the Greek word for self, and autocorrelation means data that is correlated with itself, as opposed to being correlated with some other data. Consider the nine values of Y below. The column to the right shows the last eight of these values, moved “up” one row, with the first value deleted. Autocorrelation refers to the degree of correlation between the values of the same variables across different observations in the data. The concept of autocorrelation is most often discussed in the context of time series data in which observations occur at different points in time (e.g., air temperature measured on different days of the month).
