by state: gen lag1 = x [_n-1] If there are gaps in your records and you only want to lag successive years, you can specify. . sort state year . by state: gen lag1 = x [_n-1] if year==year [_n-1]+1. // a combination foreach v in x y { tsrevar L (1/10).`v' rename (`r (varlist)') `v'_#, addnumber } If the purpose is to create lagged variables to use them in some estimation, know you can use time-series operators within many estimation commands, directly; that is, no need to create the lagged variables in the first place.

Stata has no -lag- command. It does support a lag operator L (see -help varlist-?) 2.

## Oct 20, 2020 The most basic way to use LAG is COMPUTE V1 = LAG(V2) . This simply computes a (possibly new) variable V1 holding the value of the previous

In the case of a linear regression with lagged independent variables, what are the techniques for dealing with the NA values introduced by padding lagged variables (since t < 0 values do not exist)? I ask because I'm implementing a random forest with lags and have to …
been the generalized method of moments (GMM) that relies on lagged variables as instruments. This method been incorporated into several widely available software packages, including SAS, Stata, LIMDEP, RATS and plm (an R package) , usually under the name of Arellano-Bond (AB) estimators.

how to create 1st and 2nd lag for variables in panel data and how to create first difference in panel data using STATA Or should i include lagged variable and use the dynamic panel or I would like to run a panel fixed-effects regression in STATA and lag all independent variables by one quarter to The decision to include a lagged dependent variable in your model is really a theoretical question. It makes sense to include a lagged DV if you expect that the current level of the DV is heavily determined by its past level. In that case, not including the lagged DV will lead to omitted variable bias and your results might be unreliable.

It is as I said originally: with -xtset qnno year-, Stata will interpret the lagged value to mean the value from the year before, and there is never any such observation in your data: it's always either 2 years or 4 years before. The -delta- option won't rescue us because there is no regular interval we can tell Stata to use. Stata has no -lag- command.

### But the use of lagged variables is a fairly common approach when dealing with simultaneity bias in general and creating instrumental variables in particular. Say you have a feedback between two variables in your model: the independent variable (such as price) and the dependent variable (such as quantity). Then both are endogeneous (their causes

Autoregressions (AR) and Autoregressive Distributed Lag (ADL) Models identifier variable and j() the new episode identifier variable created by. Stata. All constant variables are The Lag-Operator “L.” uses the observation in t-1. The correlation of a series with its own lagged values is called autocorrelation or serial correlation.
