### Re: Clustered errors

Hi, I have a cross-sectional dataset of 130 observations. These observations are selected over 20 different countries, for different periods in time. I do not have an equal number of observations for each country, nor do I have equal time periods for each observations. Eg: 3 observations for country...

### simulate CV structural break

Hi,

Does anyone know how you have to simulate critical values for a unit root when your series contains a structural break?

### Re: ARIMASel (Automatic ARIMA selection)

Because a VAR Object with only one endogenous variable and no exogenous variables is the same as an AR model of that variable with the same lags. (regressioncoefficients, standard deviations, t-values are all the same- so why wouldn't the optimal lag length be?)

### Re: ARIMASel (Automatic ARIMA selection)

Hi, When I use the add-in to determine the optimal AR lag length of a series I get an AR(1) according to the Hannan-Quinn criteria. When I estimate the same model as a VAR-object with the same series the Hannan-Quinn criteria points at an AR(5). I entered 10 lags as maximum lag length in both the Ad...

### Re: ARIMASel (Automatic ARIMA selection)

I have to determine the appropriate AR specification of at least 100 series. I want eviews to save the recommended specification under the same (or a slightly adjusted) name as the series. Is it possible to program this or do I as have to replace chosenstr (in your example) by the seriesname each ti...
