Spss syntax help please

[indian saint]

I have one variable with more than thousand observations.
I need 100 random samples of size 5.
Then I need a new variable contains sum of each sample.That is new
variable will consist of 100 observations.

Can anyone help me pls...........

open a new instance of SPSS. Copy and paste the syntax below into a
syntax window.
Is this what you want to do?

* make up data.
new file.
set seed = 20091209.
INPUT PROGRAM.
LOOP id=1 TO 1000.
COMPUTE existingvar = rv.normal(0,1).
END CASE.
END LOOP.
END FILE.
END INPUT PROGRAM.
FORMATS id (F4.0) existingvar (f6.3).
descriptives variables = existingvar /statistics = all.
* now have data analogous to your description.
compute ranvar= rv.uniform(0, 2e31).
sort cases by ranvar.
compute newsequence= $casenum.
select if newsequence le 500.
compute samplegroup = mod(newsequence,100) +1.
frequencies vars= samplegroup.
dataset declare aggfile.
aggregate outfile = aggfile /break = samplegroup
/meanexistingvar= mean(existingvar).
dataset activate aggfile.
descriptives variables= meanexistingvar /statistics= all.

That example syntax draws the samples without replacement of the cases
into the pop for the next draw.

Thank you very much for your help. But the programme gives sample
without replacement.I need with replacement.

See if this helps:

I used the code posted there to sample with replacement in order to
create a demonstration of the sampling distribution of the mean.

thanks yar,let me check it.

Apologies for top-posting, but it seemed appropriate under the
circumstances!

Yafaa, you posted exactly the same message with subject line "PLS
regression etc.". Posting it twice is not helpful.

Also, you might have better luck at the SPSSX-L mailing list, which is
far more active than this newsgroup these days. The mailing list can be
viewed here:

http://spssx-discussion.1045642.n5.nabble.com/

Notice that if you post via Nabble, you can include attachments
(although they will only be available to people who read the list via
Nabble).

HTH.

I have the Julie Pallant's Book ''SPSS Survival Manual'' it's a huge help, I know how to do many things on SPSS now thanks to her; but unfortunately there's no chapter for PLS Regression ... Therefore, if anyone can share his/her knowledge and expertise that will be great.

In my opinion, it is as it allows to determining the direction of the relationship between the variables, and the strength of the relationship; but also calculating the coefficient of determination and assessing the significance level.
