Extending Sample Size

[george m]

How does one extend sample size (i.e. past the last observation originally defined) using a command?
thanks,

[EViews Gareth]

Look up the pagestruct command.

great, thanks!!

Greetings!
In my programming, I want to increase the size of arrays in my work file to 10000 from the original 2715 observations. But Eviews 7 does not support "expand" meanwhile the examples of pagestruct in the user's manual does not explain explicitly enough to me.
I just want to know how to use pagestruct to do so explictly.
Thanks a lot

Code: Select all

pagestruct(start=1,end=10000)

the code I find is as follows:

Code: Select all

load "c:\users\yang\documents\shanghai composite index.wf1"
rndseed 12345
!nreps=10000
series rt
series u
series h
series min
series max
series l1
series s1
scalar mcrrl
scalar mcrrs
rt=log(sh/sh(-1))
equation eq1.arch(m=100,) rt c
eq1.makegarch h
pagestruct(start=1,end=10000)
series hsq=h^0.5
series resi=rt-@coefs(1)
series sres=resi/hsq
eq1.forecast rtf yse hf
'bootstrap loop
for !z=1 to !nreps
  smpl 3 2715
  group g1 sres
  g1.resample
  smpl 2716 2725
  rt=@coefs(1)+@sqrt(hf(-2715))*sres_b(-10)
  sh=sh(-1)*exp(rt)
min(!z)=@min(sh)
max(!z)=@max(sh)
next
smpl 1 10000
l1=log(min/1138.73)
mcrrl=1-(exp(-1.645*@stdev(l1))+@mean(l1)))
s1=log(max/1138.73)
mcrrs=(exp((1.645*@stdev(s1))+@mean(s1)))-1

It warns that "Incomplete WFSTRUCT" specification in "PAGESTRUCT (start=1, end=10000)"
I am total lost in it.
Thanks a lot for your advice.

I did not leave space in the syntax mentioned above: pagestruct (start=1, end=10000)
but after I leave space between pagestruct and the bracket, it warns that start=1 is not defined in "pagestruct (start=1, end=10000)
I feel hopeless now

What version of EViews are you using? And is it uptodate?

[yxr]

the version is 7.2

I attached the data and programming code here. Thank you very much, Eviews expert.

[startz]

I suspect the problem is that your pagestruct isn't compatible with your workfile structure. But I'm not sure.
Try this. Take out the load statement and the pagestruct. Load the workfile in manually and use Proc/Structure Resize to extend it manually. Then run the rest of the program.

[yxr]

Yes, it works.
But after 5 minutes, it says that:
syntax error:

Code: Select all

mcrrl=1-(exp(-1.645*@stdev(l1))+@mean(l1)))

where is the mistake?
Thanks a lot.

[startz]

Your parentheses are unbalanced.

How foolish I am!
Thank you very very much,Startz. You are so wonderful!Pay Homage to you!
