hi every body ..

im a new member and i have a problem with my thesis, estimation part exactly .. i wonder if you can help me .. hope you can as soon as possible.

my problem is: i dont know what the type of my data and how i can organise it in eviews..
my model is gravity model .. the dependent variable is exports between 17 countries .. in each observation y = export from country i to j in 1996 , 1997 , 2007, 2008
there are 4 years

the independent variables is
GDPi
GDPj
CAPITA ( the difference between gdp per capita in each pair of countries)
DIST (geographic distance between each pair of countries)
and 3 dummy variables BOR, REGN, GAFTA.

Please tell me what the type of my data and how i can put it in eviews and estimate it ,also how i can deal with dummy varibles?

please if you can help me insert some images to explain the prosses

my data shown in the attached file ..

thank u very much..

please .. help me if u can

You can use panel data analysis to estimate your gravity model. Please follow this link on creating a panel workfile http://forums.eviews.com/viewtopic.php?f=7&t=74

I downloaded also your data and will analyze it when i have time.

thank you bensamen very much .. but my main problem is:

1) is my data pool data or panel data and what the difference?

2) what the main sectors i must identify in the "pool" object?
like this

_ alg
_ bah
_mor
_sau


or by pairs of counries, like:
_ alg bah
_ alg jor
_ alg mor
_ alg sau

then the second country
_ bah alg
_ bah jor
_ bah mor
_ bah sau

please help me ..

We often loosely use the term panel data to refer to any dataset that has both cross-sectional and time-series dimension. More precisely it’s only data following the
same cross-section units over time. Otherwise it’s a pooled cross-section. After looking at your data, i can suggest to use cross section because you dont first have an regular time series (1996 , 1997 , 2007, 2008).
So far, i dont know the purpose and hypothesis on your studies but when dealing with such data, we practically estimate a cross section regression by year (smpl if year=2007 and then do regressions).

thank you bensamen .. i will try what you tell me

regards,

Hi,

I'm sorry, I am very new to eviews, I don't even know how to post a new forum, thus I use a reply to this post as I'm having the same problem with you.

I'm using a gravity model too, to estimate the impact of immigrants on trade. My data consists of 10 countries, spanning from 1997-2008. Thus I guess it is a panel data then.

I have a few questions and I am extremely grateful if any of the users and moderators can help me.

1/ I've done the unit root test for stationary test for each variable. I just click each variable and go to VIEW-UNIT ROOT TEST. Is it the correct procedure? But it states that I did a panel unit root test then, and I want to employ pooled OLS, is ok?

2/ I wan't to employ pooled OLS, rather than Fixed Effect as I have time invariant variable (LANGUAGE, DISTANCE). However, I do not know how to generate time dummy, even as I follow the suggestion (I write a command in the generate series by equation -group dummies @expand(@year) - is this correct?) I still get the respond from eview syntac error. How do I generate the time dummy then?

Thank you so much for your kind attention to this matter. Please help. :eviews6: :eviews6:

p/s: how do attach my file here?

Hi there,

I am completely new to E-Views and I really need to carry out my own Gravity Model. The aim of my Gravity Model is to illustrate the impact of internet users on trade flows. I have read many studies and one I came across was http://www.businessjournalz.org/article ... n61617.pdf. I want to focus on the African countries and show the impact the internet can have and I am unsure as to how to carry out the model. If someone could kindly guide me step by step on how to create one I would really appreciate it.

I am thinking of taking 8 African developing countries and 8 developed countries (non-African) and test the relationship using the gravity model. I have data on distance and internet users in the countries. However I do not have a clue on how to create the dummy variables nor what other data I require and how to apply it in E-Views.

I know im asking for a lot here but honestly if someone could help me I would honestly be so grateful!

Kind regards

Ricky

Gareth if you could possibly help me it would be much appreciated,

Thanks!!

im trying to get the exact Distance between Fiji and Australia...could you help me on how to get the data on this...thank you
