WebSection 8 Models for Pooled and Panel Data Data definitions • Pooled data occur when we have a “time series of cross sections,” but the observations in each cross section do not necessarily refer to the same unit. • Panel data refers to samples of the same cross-sectional units observed at multiple points in time. WebBoth pooled cross section data and panel data contain information on different time periods. However, the difference between pooled cross sections and panel data is that pooled cross. section collects data on new individuals, firms, etc. each period while panel data follows the. same individuals, firms, etc. from one period to the next.

Nothing new needs to be done in stating assumptions!; The practically important issue is allowing for different intercepts, and possibly different slopes, across time. litiasis bucal

Webble intercepts for each cross section, are associated with this assumption. Equation (2) represents the format for pooling under fixed coefficients and com-plete homogeneity. Pooling with common slope coeffi-cients and with intercepts which vary by cross section is but one possible form of mixed pooling methods.
