I also try deeper lags but no one is significant. From my understanding, if the lagged dependent variables are not significant, the model is static and then fixed-effect and IV approach should be used to address endogeneity. Table of Contents Index EViews Help lagged values of the independent variable would ap-pear on the right hand side of a regression. 2. Statistical. In other contexts, lagged independent variables serve a statistical function. Examples in-clude dynamic panel data analysis (Arellano and 950 / Lagged Explanatory Variables Marc F. Bellemare, Takaaki Masaki, and Thomas B. Pepinsky Lagged Dependent Variables The Durbin-Watson tests are not valid when the lagged dependent variable is used in the regression model.

data sets that you will encounter in practice. They do not, however, deal with lagged effects, in which what has happened in the past helps to predict the future. We encountered one example of lagged effects, the monthly closings of the Dow Jones Industrial Average. A given month's closing tended to be relatively close to that of the previous month.

In a widely cited result, Fair (1970) shows that if the model is estimated using an iterative Cochrane-Orcutt procedure, all of the lagged left- and right-hand side variables must be included in the instrument list to obtain consistent estimates. literature on this. google for regression with lagged dependent variable and a lot of things should come up ). In that case, you need to build the likelihood and use optim or optimx because lm is not the correct approach.

The autocorrelation function at lag=1 will experience a slight decrease in correlation. At lag=12 you will have the lowest correlation of the day, after what it will begin to increase. Move forward 6 month to 1 pm. Your time series is still somewhat correlated. Move lag to 6 months and 1 am. This term belongs to the statistical analysis of time series data, where models are sometimes built in which a variable is predicted based on its past values. This is called autoregression or autoregressive models, and the values of the variable (e.g at the same time but one year earlier) would be a predictive variable, called a lagged variable.
