By using the observation for 1978 I would like to interpolate the value of 1977: sch_1977 = 0.97 * sch_1978. The code I have tried is the following: forvalues y = 1977 1976 1975 { local i = `y' - 1958 bysort cc (Year): generate sch`y' = 0.97*sch [`i'] replace sch`y' = 0 if Year != `y' …

We often have data where variables have been measured for the same subjects (or countries, or companies, or whatever) at multiple points in time. These are typically referred to as Panel Data or as Cross-Sectional Time Series Data. We need special techniques for analyzing such data, e.g. it would be a mistake to treat 200 individuals measured ... Using tsappend with panel data tsappend’s actions on panel data are similar to its action on time-series data, except that tsappend performs those actions on each time series within the panels. 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.
