He would like to use that to clean-up his dataset in R. In stata help manual: _n contains the number of the current observation. Here’s an example to illustrate what _n does: set obs 10 generate x = _n The current (time t) observation of each variable depends on its own lagged values as well as on the lagged values of each other variable in the VAR. Writing VAR( p ) as VAR(1) [ edit ] A VAR with p lags can always be equivalently rewritten as a VAR with only one lag by appropriately redefining the dependent variable. 2010-04-03 · And these X variables represent "lagged" variables, which are just the value of variables from the past months.

and for a DataFrame as input: 2019-03-06 2020-11-11 2019-07-01 I guess a solution for dummies would just be to create a "lagged" version of the vector or column (adding an NA in the first position) and then bind the columns together: x<-1:10; #Example vector x_lagged <- c(NA, x[1:(length(x)-1)]); new_x <- cbind(x,x_lagged); 2008-01-27 2017-05-18 Across the social sciences, lagged explanatory variables are a common strategy to confront challenges to causal identification using observational data. We show that “lag identification”—the use of lagged explanatory variables to solve endogene-ityproblems—isanillusion: laggingindependentvariablesmerelymovesthechannel My question is as follows -- Using R or GRETL, how is it possible to create an ARIMA/TimeSeries model with the above data to predict the SalesCurrent variable. Using simple Linear Regression, one could simply have a formula such as say, lm (SalesCurrent ~ ., data=mytable) , but it would not be a time-series model since it does not take into account the relationship between the different variables. An alternative is to use lagged values of the endogenous variable in instrumental variable estimation. However, this is only an effective estimation strategy if the lagged values do not themselves belong in the respective estimating equation, and if they are sufficiently correlated with the simultaneously determined explanatory variable.
