Including lagged dependent variables can reduce the occurrence of autocorrelation arising from model misspecification. Thus accounting for lagged dependent variables helps you to defend the existence of autocorrelation in the model. Lagged dependent variables are commonly used as a strategy to eliminate autocorrelation in the residuals and to model dynamic data generating processes. The fixed effects and lagged dependent variable models are different models, so can give different results. We discuss this on p.

The essential nature of the problem can be illustrated via a simple model which includes only a lagged dependent variable and which has no other explanatory variables. Imagine that the disturbances follow a ﬂrst-order autoregressive process.

The three dimensions are: The potentially confusing part for modelers is 2. SPATIALLY LAGGED DEPENDENT VARIABLES In this chapter, we describe a statistical model that incorporates spatial dependence explicitly by adding a “spatially lagged” dependent variable y on the right-hand side of the regression equation. This model goes by many different names. Anselin (1988) calls this the spatial autoregressive If an independent variable (x) has a lagged effect on dependent variable (y) of a OLS regression model, you must insert its lagged value and not current value in time series data.

Maybe this can help #store your model model<-your_model #get the last pt observation last<-dato[nrows(dato$pt), c('pt', 'age')] years<-12/4
If so, then the portion which is unexplained by the lag is instead explained by the other right hand side variables.

This model goes by many different names. Anselin (1988) calls this the spatial autoregressive Lagged dependent variables are also utilized as a means of capturing the dynamics of politics. In the study of public opinion, for example, there are theories in which an attitude at time t is a function of that same attitude at t 1 as modiﬁed by new information.

2. If the data are nonstationary, a problem known as spurious regression
Lagged Dependent Variables. The Durbin-Watson tests are not valid when the lagged dependent variable is used in the regression model. In this case, the Durbin h test or Durbin t test can be used to test for first-order autocorrelation.
