Is there a way to plot residual autocorrelation (ACF, PACF) of Y in n=1 time-series analysis? |
|
|
Autocorrelation plots are available. I don't know what you mean by residual autocorr plots. |
|
|
If I fit a n=1 time-series model with covariates shown below I can plot the raw autocorrelation function of Y. However, is there a way to plot the autocorrelation function of the residuals of Y? Y ON X1 X2 X3; I red about RDSEM and tried the following code to model e.g. AR(2) model. Y ON X1 X2 X3; Y^ ON Y^1 Y^2; But there is no way to obtain ACF of Y^ in order to have a clue on the autocorrelation pattern needed? |

I would recommend to keep increasing the lag until the new autocorrelation is no longer significant. For example, if you estimate Y ON X1 X2 X3; Y^ ON Y^1 Y^2 Y^3; and the coefficient in front of Y^3 is no longer significant I would conclude that lag 2 is enough. You can go a bit further to make sure that something cyclical is not happening. |

Thanks! |

Is it possible to define residual autocorrelation structure for between-level response variable? I tried but got the warning below: "Variables specified on the BETWEEN option cannot have lag and be mentioned on the LAGGED option." |
|
|
What does the Between level portray? Why is time on Between? |
|

Yes, I know the setup is a bit awkward. I have a response variable that has been measured annually (i.e., N=1 time-series) for some 80 years (=between-level) and I'd like to know how some IVs measured several times within years (=within-level) influence the response's variation at the between-level. Can such a model be fit? I guess it would be a bit like adding a spatial autocorrelation into the model? |

Maybe you could try the auto-regressive approach of UG ex6.17 and somehow apply it to the Between level. |
