Re: x13 tells me series has no estationality, but...

Very sure. The strange issue is x13 gives me the seasonally adjusted series, irregular and trend series.
But the message posted made me suspicious.

x13 tells me series has no estationality, but...

i'm quite sure it has. This is the error i get: WARNING: Series should not be a candidate for seasonal adjustment because the spectrum of the original series (Table A1 or B1) has no visually significant seasonal peaks. Why am i sure? because i'm working with labour force and employed people. Everywh...

Re: Tramo Seats or X13 for seasonal adjustment?

I worked with Multiplicative composition over x13. So, as you mentioned, i just need to scale for 100.
Thanks a lot for your consideration. Really.

Tramo Seats or X13 for seasonal adjustment?

Hi I need to chose which method to perform a seasonal adjustment. I will use the criteria of less or minimum noise, ie, irregular component. But, how can i compare the Irregular series from Tramo/Seats against the irregular series from x13? I did it, but Tramo/Seats reports values around 100, and x1...

Doubt adjusting seasonally with X13

Hi I have a doubt i wish you enlighten me. I have 30 obs. And i give the order to eviews to adjust seasonally by x13. I select the option choose best model with limits. However, all the models estimated show None of the models were chosen And then if i compare the series produced by x13 is the same ...

vector to series?

Hi
Programming i create a vector. The problem is the vector lost the related dates. How can i import the date, for example, from TC_data to the vector BETAS? I need it because i must graph and i really need specify the dates. Any idea? Thanks for your time and help.

i've been searching and i found a code @mprior or @vprior, but neither the manual nor on the forum detail how to use those functions.

Re: Kalman filter and NAIRU, declaring space/state

Ok, it runs flawless. I haven't check the accuracy of the estimation. But, if i want to declare initial states for the variables, how do i make it? can you give me a link? By the way, thanks for your help. Not even in weeks i'd would have made it. Thanks again.

Re: Kalman filter and NAIRU, declaring space/state

But in the paper, the author says h and x are unknown. He clearly says those equations represent states. But under eviews, they should represent @signal? I want to declare i really don't know Kalman implementation. The only data i have is Y and U, which are gdp and unemployment. The paper illustrate...

Kalman filter and NAIRU, declaring space/state

Hi I'm replicating a paper, which modelled the NAIRU like this: http://img804.imageshack.us/img804/2111/kalmannairu.jpg equation 1 says output is equal to a tendency, h, and a cycle, x. Eq 2 says the tendency is explained by a tendency also, g, and a random error. Eq 3 explains that tendency g. Eq4 ...

Here is my code for a arch and garch processes. The problem is i'm not generating dates associated to simarch/simgarch, so when i try to show a correlogram, i get a malfunction error.
