NettetTime series data is data is collected for a single entity over time. This is fundamentally different from cross-section data which is data on multiple entities at the same point in time. Time series data allows estimation of the effect on Y Y of a change in X X over time. This is what econometricians call a dynamic causal effect.
NettetAs I understand, one of the assumptions of linear regression is that the residues are not correlated. With time series data, this is often not the case. If there are autocorrelated residues, then linear regression will not be able to "capture all the trends" in the data.
