looping in VAR

[nic_sun]

I have a sample of 40 countries (id =1,2,...40) with variables x and y (x1,y1,x2,y2...x40,y40) . I wanted to loop in VAR with some specific conditions. For example,if a country has an id 4,7,10,15,32,34 I want to use lag length of 1, but if country has an id 1,2,9,11,23 I want to use lag length of 2, if a country has an id 19,33,20 I want to use lag length of 3 and for other lag length of 4. I use a following sample code:

Code: Select all

for !j=1 to 40 if !j=4 or 7 or 10 or 15 or 32 or 34 then var m{j}.ls(p) 1 1 y{j} x{j} else if !j=1 or 2 or 9 or 11 or 23 then var m{j}.ls(p) 1 2 y{j} x{j} else if !j=19 or 33 or 20 then var m{j}.ls(p) 1 3 y{j} x{j} else var m{j}.ls(p) 1 4 y{j} x{j} endif endif endif endif next

However, eviews gives me the syntax error for this. Any help in this regard will be highly appreciated.

A line like:

Code: Select all

if !j=4 or 7 or 10 then

should be:

Code: Select all

if !j=4 or !j=7 or !j=10 then

A line like:

Code: Select all

if !j=4 or 7 or 10 then

should be:

Code: Select all

if !j=4 or !j=7 or !j=10 then

Thanks. But, still I get the error . Can I have an extra hint?

What error message do you receive?

What error message do you receive?

Still the syntax error
I think the last line code is wrong. Do I have to still write the if condition for last condition. There are 4 conditions but I only wrote three conditions and I assume that if they are not satisfied it will run the VAR with the order 4. Am I correct?

[EViews Gareth]

You are correct. However you have three "if" statements and four "endif" statements. There's probably something going wrong there.

Thanks once again for the input.

Try to delete the else and use just if, not nested :

for !j=1 to 40
if !j=4 or 7 or 10 or 15 or 32 or 34 then
var m{j}.ls(p) 1 1 y{j} x{j}
endif
if !j=1 or 2 or 9 or 11 or 23 then
var m{j}.ls(p) 1 2 y{j} x{j}
endif
if !j=19 or 33 or 20 then
var m{j}.ls(p) 1 3 y{j} x{j}
else
var m{j}.ls(p) 1 4 y{j} x{j}
endif
