@elem EV6

[terryus]

Hi,

I need your help related to @elem in Eviews 6.....

I have a serie X from 1980 to 2008. I wanted to do a FOR loop to extract since
2000 to 2008 values:

For !i = 2000 to 2008
scalar x(!i)=@elem(x, "!i")
Next


But did not work!!! :( , show a error related to string....

Can you help me, I need it really....

thank you very much.

Code: Select all

For !i = 2000 to 2008 %date = @str(!i) scalar x(!i)=@elem(x, %date) Next

Hi Gareth,

This is very helpful. I am a rookie Eviews user. How can I apply this to monthly data?

Thanks!!

What is it you're trying to do?

[rowy]

I am trying to check for zero's in the series, if so, set it to previous month value, else let it be. but the @elem function didn't like my @str(%date).

for !j=2005 to 2010
for !i=1 to 12
%date=@str(!jm!i)

if @elem(price_mpr_sm,%date)=0 then
@elem(price_mpr_sm,%date)=price_mpr_sm(-1)
else
@elem(price_mpr_sm,%date)=price_mpr_sm
endif
next
next

Can't you just do:

Code: Select all

price_mpr_sm = @recode(price_mpr_sm=0, price_mpr_sm(-1), price_mpr_sm)

without worrying about loops etc...

Fantastic!! Thanks so much!!
