small. I g

Seems to me that the notion of power in a pilot study is moot. Typically, a
pilot study is a test of the research methodology and instruments. As such,
your sample size is a pragmatic decision and should consist of enough
observations to test your design and research instruments. For instance, i

Lorenzo, your problem is not clear to me.
Are you trying to deal with the analysis of the actual sampling
that you describe, to find out for those particular 100 instances
what the most frequent five numbers happen to be?
Or are you trying to compute the relative frequencies of particular
My problem is a frequency count similar to this:
One hundred times (cases) I take five different
balls from a container with one hundred balls.
Every ball is numbered from 1 to 100.
After one hundred extractions I want to compute
exactly the twenty balls more frequents.

I could use help on two questions that I haven't been able to adequately

1) When performing a multiple linear regression we have examined t-tests for
the null hypothesis that a coefficient is zero. If we examined the tests

it is a fundamental one. We all know that linear regression can be
accomplished by matrix multiplication and that there are packages which will
do it for you. I am teaching myself C++ and for the purposes of the

Does anyone have any info about wilks' test ?
