Re: Automatic lag length selection - Panel Unit Roots

Finally, the answer! I was running the unit root test over the same series, and with this, the AIC obtained with lag 0 was -2.855214. However, this unit root used 11 obs, while with the lag 1 we have only 10 obs. Now, if I restrict the first unit root to use only 10 obs I get the same result as you,...

Re: Automatic lag length selection - Panel Unit Roots

Yes, I used a common sample. Actually, I have just found that this problem(*) also happens with unit root tests on time series. If you would like to replicate the problem here goes: (*) I'm not sure if it is really a problem, yet. -Given the two series: y1t: -0.02889473846674593 -0.00656501803350378...

Automatic lag length selection - Panel Unit Roots

Hi! Is the information criteria used in Panel Unit Root Tests (like the Fisher ADF) to select the lag length calculated by the formulas given in the Eviews help file? E.g.: In the help I found the following Akaike definition: AIC = -2*(l/T) + 2*(k/T) where l is the value of the log of the likelihood...

Dickey-Fuller p-value

Hello there! I would like to know if is there any statistical distribution function that returns the p-value for the ADF t-stat. Something like the @tdist() function, but with the ADF distribution. I read in the help that Eviews uses MacKinnon (1991, 1996) critical value calculations. How can I acce...

Re: Panel data export

If I correctly understand what you want I would do something like this: Let's say you have a table with each row representing an equation that you would like to estimate, and each column representing a variable. The first, obviously, is the dependent variable. Name this table as "specifications...

Re: correct string form for running regression

What happens if you try this:

%hour = "1"
%estimate = {"est_"+%hour}
myequation.ls {%estimate}

Re: Panel data export

Alternatively, you can do it without the new function: 1 - Fit the equation to a temporary series: eq01.fit(u,f=na) tmp_series 2 – Lets say your equation is specified as: y=c(1)+c(2)*x1+c(3)*x2. Then you can generate a series with the fixed effects with: genr fix_effects=tmp_series-(eq01.@coefs(1)+e...
