Se hela listan på stats.idre.ucla.edu Basically, Stata treats each time period as an integer. The integer records the number of time units (whatever you define them to be) that have passed from an agreed-upon base, which for Stata is 1960. For example, for 100 quarterly data ions observatthat start in 1960 we could generate Stata dates using . set obs 100 generate date = tq(1960q1 In time series data there is a variable that serves as index for the time periods. That variable The stata commands to generate the first lag and second lag are. We simply use generate time_var to define a variable equal to _n . gen rw_1a = L.rw // lags using Stata's L. operator .
