Stata 5: How do I create a lag variable. Title Stata 5: Creating lagged variables Author James Hardin, StataCorp Create lag (or lead) variables using subscripts.

Nonetheless, it can be very helpful to have a file of commands that are executed, rather than simply typing them in one at a time. A time series data set may have gaps and sometimes we may want to fill in the gaps so the time variable will be in consecutive order. This involves two steps. First of all, we need to expand the data set so the time variable is in the right form. When we expand the data, we will inevitably create missing values for other variables.

Generate lagged variables stata

This follows because you want to average across variables here, not observations. 3. -rowmean()- does not support time-series operators, so you need to create the corresponding lagged variables The first variable in the tsset command should be id (whatever it is in your dataset, e.g., country, region, household, etc.). If you add gdp in that command, Stata uses gdp for identification of each observation, i.e. treats each entry as independent from the rest, thus, there couldn't be any lags. The variable names you use in your example are too long and cryptic for me to want to take a detailed view at your code.

gen lead1 = x [_n+1] You can create lag (or lead) variables for different subgroups using the by prefix. You can loop to do this but you can also take advantage of tsrevar to generate temporary lagged variables. If you need permanent variables, you can use rename group to rename them.

drop-down menu, choose the variable or variables you wish to sort on, and then click “OK.” Do Files: Stata can be used interactively – just type in a command at the command line, and Stata executes that command. Nonetheless, it can be very helpful to have a file of commands that are executed, rather than simply typing them in one at a time.

Generally speaking, I find using STATA for creating lagged variables to be a bit unwieldy. I use PROC SQL in SAS to create the multiple lags I need (I'm currently dependent variable to explanatory variables. With time series new issues arise: 1 . One variable can influence another with a time lag. 2.

Stata will generate a new variable, and for each of the observations, it will evaluate the expression specified according to the values in the variables we use in the expression. In the first example, for an observation with an income of 200, income_squared will contain 40,000, but for an observation with an income of 100, income_squared will contain 10,000.
