I am experimenting errors with AGGREGATE with version 0.10.1-g1082b8 of PSPP. Specifically, the computed values of the aggregated statistics are not valid. SPSS does correctly the computation, but not PSPP. Do someone knows why? Or is it a bug?

Here is our syntax.

* ......................................................................................................................................
* Aggregate PVIREAD statistics by PROVINCE.
* PV1READ is a variable from the PISA 2009 data file for reading achievement.
* PROVINCE is a previously created variable for the Canadian sates.
AGGREGATE
/OUTFILE=* MODE=ADDVARIABLES
/BREAK=PROVINCE
/PV1READ_MEAN = MEAN(PV1READ)
/PV1READ_SD = SD(PV1READ)
/PROVINCE_N = NU(PV1READ).
* ......................................................................................................................................

Best regards.

Thank you for your report.

Can you give the _complete_ syntax including the data definition so that we can
try to reproduce the problem.

Please also post the result you get, *and* the results that you expect, AND say
specifically why you think the results you see are incorrect.

That way, we can investigate, and decide if indeed there is a problem, and if so
we can fix it.

Thank you.
