To work within panels, a panel variable must have been speciﬁed with tsset or xtset. It does not matter which command you use; the two are equivalent.Two elements are immediate. First, the panel structure is crucial here. For each panel, we must identify the first (or perhaps last) occurrence of a state, say, state == 1.
