"SPLAGVAR: Stata module to generate spatially lagged variables, construct the Moran Scatter plot, and calculate Moran's I statistics," Statistical Software Components S457112, Boston College Department of Economics, revised 09 Aug 2012. 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.

Nowadays, mixed modeling is probably the most popular approach to longitudinal data analysis. But including a lagged dependent variable in a mixed model usually leads to severe bias. In economics, models with lagged dependent variables are known as dynamic panel data models. 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.

In statistics and econometrics, a distributed lag model is a model for time series data in which a regression equation is used to predict current values of a dependent variable based on both the current values of an explanatory variable and the lagged (past period) values of this explanatory variable. 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.

* In economics the dependence of a variable Y (dependent variable) on another variables(s) X (explanatory variable) is rarely instantaneous.

Dependent variable (Y) is the total return on the stock market index over a future period but the explanatory variable (X) is the current dividend-price ratio. + =α+β + +t h t t h Y X e , h is forecast horizon Yt+h is calculated using the returns Rt+1, Rt+2,.., Rt+h.
