Hello all,
This is probably not related to db2 but due to fabulous responses i
got earlier for my questions, i am convinced that this forum is full
of smart people.
Here is question:
I have data rows say count of 3000 which i got from sql. i call this
universe.
Now i need samples out of this universe. say my sample size is 45.
this is for audit and samples are random rows picked from universe. i
can use random functions but business people does not want it that
random. so i divide universe by sample and start from first row of
universe skipping universe/sample rows and created a sample. There are
more complications to it but not relevant here. My questions is if
there is some statistical/mathematical formula or way to do this
same thing say pick rows from large dataset which are equally
distributed ( i might not be using the right term "equally
distributed").
Regards,
