You can create lag (or lead) variables for different subgroups using the by prefix. For example, . sort state year . 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.

which returns a durbin and hausman wu of above 0.4 each respectively. When your data is in long form (one observation per time point per subject), this can easily be handled in Stata with standard variable creation steps because of the way in which Stata processes datasets: it stores the entire dataset and can easily refer to any point in the dataset when generating variables. SAS works differently. 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. how to create 1st and 2nd lag for variables in panel data and how to create first difference in panel data using STATA

The only additional information required to implement this command are the latitude and longitude of regions. More importantly, the spgen A few days ago, my friend asked me is there any function in R to generate lag/lead variables in a data.frame or did similar thing as _n in stata. He would like to use that to clean-up his dataset in R. In stata help manual: _n contains the Here the final data would be 4 800 observations (4 variables X 30 occasions X 40 subjects) nested in 40 subjects. I would like to test separately (not for model comparison) for : simultaneous (synchronous) effects : the influence of x1, x2, and x3 at time t on y at time t. lagged effects : the influence of x1, x2, and x3 at time t-1 on y at time t. You can create lag (or lead) variables for different subgroups using the by prefix. For example, .

You might be lagging twice when you use the L in the model on an already lagged variable. Remember that STATA has the menu where you can simply go to xtgls, xtreg, etc, etc, options and look for

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.

If you just specify panel and year variables, Stata expects unit spacing, so lag 1 with yearly data means "the previous year". Asking for a lag 1 variable is legal, but all values are missing. xtset ID Year gen lag1 = L1.Y If you specify delta(5) then a lag 1 variable is missing in all but two observations. xtset ID Year, delta(5) gen lag5 = L1.Y

sort state year . 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. Recorded with https://screencast-o-matic.com I want to create 10 lags for variables x and y. Now I create each lag variable one by one using the following code: by ticker: gen lag1 = x[_n-1] However, this looks messy. Can anyone tell me how can I create lag variables more efficiently, please?

- 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. The Moran's I p-value displayed on the Moran scatter plot is calculated using a random permutation The variable group defines the different groups of our data and the variable values contains corresponding values. Example: Create Lagged Variable by Group Using dplyr Package In this example, I’ll illustrate how to use the functions of the dplyr package to add a new column with lagged values for each group to our data frame. lagged values of the instruments are available). This estimator is available in Stata as xtabond.

Similarly to xtdpdsys, it uses the instrumental variables of endogenous variable as lags in levels and differences. This is not an official command in Stata, but it is

xtset ID Year gen lag1 = L1.Y If you specify delta(5) then a lag 1 variable is missing in all but two observations.

Hi all ! I'm new to this forum, and also newbie in Stata. I try to generate a simple lagged variable using the syntax : l.var but I've got an

Most commands in Stata allow (1) a list of variables, (2) an if-statement, and (3) options. 1. A list of variables consists of the names of the variables, separated with spaces.
