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, … 2017-08-15 Stata has no -lag- command.

This simply computes a (possibly new) variable V1 holding the value of the previous We often wish to create leads or lags of certain variables and Stata needs to know what variable in our set it should identify with the time (much more on this below) past and current values of growth & other (lagged) explanatory variables. • Forecasting is Stata: tsset time gen ln_CPI=ln(CPI) gen ln_CPI_1stlag=ln(L1.

Chapter 8: Regression with Lagged Explanatory Variables • Time series data: Yt for t=1,..,T • End goal: Regression model relating a dependent variable to explanatory variables. With time series new issues arise: 1. One variable can influence another with a time lag. 2. If the data are nonstationary, a problem known as spurious regression Variables related to each other over adjacent time steps, originally in the context of dynamic Bayesian networks (Wikimedia user Guillaume.lozenguez, CC BY-SA 4.0) Turn a nonlinear structural time-series model into a regression on lagged variables using rational transfer functions and common filters, I'm unsure of how to do an endogeneity test as I'm unsure whether a twice lagged variable would be appropriate as an IV, since the reg3 model gave no significant results. I did a 2sls endogeneity test : ivregress 2sls d.lenrolment d.avgmat (l.d.tuition = l2.tuition) estat endog. which returns a durbin and hausman wu of above 0.4 each respectively.

- Davis LAGS AND CHANGES IN STATA Suppose we have annual data on variable GDP and we want to compute lagged GDP, the annual change in GDP and the annual percentage change in GDP. splagvar generates spatially lagged variables for both dependent and independent variables repectively listed in varlist1 and varlist2, constructs the Moran scatter plot, and calculates Moran's I statistics to test for the presence of spatial dependence in the variables listed in varlist1.

Economists have known for many years that lagged dependent variables can cause major estimation problems, but researchers in other disciplines are often unaware of these issues. Stata also understands operator(numlist).
