hi
i try estimate a vecm. but i don,t know for impulse response function and variance decomposition
i should do vecm ... view....impulse response, variance decomposition
or
var... view...impulse response, variance decomposition
????

plz help me.......................

Hello, I want do vecm. I have 5 I(1) series. How do I construct an error-correction model? i want u]ecm(-1) or coefficients for speed of adjustment of variables.[/u] I read this page: http://forums.eviews.com/viewtopic.php?f=4&t=8508 and this: http://www.google.com/url?sa=t&rct=j&q= ... ...

if we have quarterly data for ten years , then we should select 40 periods?
40 periods is optimal ?

thanks
but is it dependent to our data?

hi every body
i have quarterly data for 10 years. i try estimate a var model. in var variance decomposition box in eviews how select periods?
eviews select automaticlly 10 periods
thanks

please help me...

can one help me????

hi
i estimate a var model. i have 2 i(0) variables and 4 I(1) variables.
can i run this var model? Can i run this model by taking the first difference of first three variables and use 2 variable at level?
do I need cointegration test?
:(

hi
i know unit root test in time series (annual data) is different with unit root test in quarterly data.

hi
i have quarterly data
how can i do unit root test in quarterly data in eviews 8?

ok. thanks. i test it.

thanks. how i apply this test in eviews8? can you tell me it step by step? please.

HI
i need apply causality test in panel data. my equation is : y= a0+a1 X + a2 Z + ... + E
that x , z are major variable in my model. now, how i can test causality between (Y,X,Z).? I have eviews 7
