A problem in working with "FOR" Loop

[eisamabodian]

i have problem, when i want to run this program:

Code: Select all

for !k=-7 to 0 step 0.001 equation equ1.ls y c x*(x<=!k) x*(x>!k) m1 m2 m3 series ssr11(!k)=equ1.@ssr series kkk(!k)=!k next

this is a threshold model.i must save SSR and !k for each equation.
but negative index or decimal values are not acceptable as index for !k.
please help me.

What are you hoping to do with this:

Code: Select all

series ssr11(!k)=equ1.@ssr

[startz]

Make two vectors. Store the argument k in one and the result in the other. Then index by 1,2,3...

[eisamabodian]

I want to save SSR of each equation and also !k values.

[EViews Gareth]

Yes, but what exactly are you doing with that line? Explain in words what it is doing.

[eisamabodian]

Yes, but what exactly are you doing with that line? Explain in words what it is doing.

I want to save SSRs of equations and also their correspondent !k.
In threshold regression approach i must sort these variables to obtain minimum
SSR and its correspondent !k.in this situation !k is threshold value for this equation.

Make the loop for 1 to 700. Then calculate the corresponding k.

Make the loop for 1 to 700. Then calculate the corresponding k.

This loop has 7000 numbers not 700.Another problem is this loop is for negative numbers not positive.these numbers are decimal and negative.Unfortunately Eviews doesn't accept any negative or decimal number as index.How can I solve this problem?

Make the index 1 to 7000. .Then store the values of k in one vector and the results you want in an other. Both indexed by 1 to 7000

Make the index 1 to 7000. .Then store the values of k in one vector and the results you want in an other. Both indexed by 1 to 7000

How can I create an index from 1 to 7000?
But I need to build an index from -7 -6.999 -6.998 ........-0.003 -0.002 -0.001
Because step is 0.001
But the question is that how can I build an index from 7000 to 1 or vice versa ?Although as I said I need index in decimal form,but it seems that in Eviews we can not build indexes in decimal form.

Roughly,

for i= 7000 to 1 step -1
k(i) = i/1000
ssr(i) = result
next

Hello,

I have a problem with !x loop.
Since I have negative values in !x, I cannot produce outputs of val_{!s}_{!y}_{!x} for negative ones.

for !s=1 to 3
for !y=1 to 6
for !x=-6 to 12
series val_{!s}_{!y}_{!x} = @recode(sp{!s}=1, y{!y}({!x}), 0) 'It does not produce outputs for negative !x's.
next
next
next

As a solution, I tried to sum all !x values with a constant number (such as 10), but it did not work. Please see below;
series val_{!s}_{!y}_{!x+10} = @recode(sp{!s}=1, y{!y}({!x}), 0)

I will be happy if someone helps me.
Best

Code: Select all

for !s=1 to 3 for !y=1 to 6 for !x=-6 to 12 series val_{!s}_{!y}_{!x} = @recode(sp{!s}=1, y{!y}({!x}), 0) 'It does not produce outputs for negative !x's. next next next series val_{!s}_{!y}_{!x+10} = @recode(sp{!s}=1, y{!y}({!x}), 0)

Its probably because series names can't have a negative sign in them, and you're using !x as part of the series name.

[serkan]

Yes it is.
Is there a solution to covert the name of the series while using negative values in !x loop? Like multiplying by -10? Or what do you recommend?
Thanks

Simplest is to use the @makevalidname function.
