Jason,
I’m going to have to heartily agree here. My first thought, when you ask how to
“analyze” your data, is that this is a fairly broad term, and the answer will
depend entirely on what your question is. I would encourage you to think in
terms of parameter estimations. At the end, you will h
Technically the definition of the nat log of zero is actually an asymptote.
What does zero mean in your data? That is the key issue you must approach
before modifying the information. If zero means "too small to measure but
not likely zero," then you can do some decimal estimation or I think you

In my experience it is possible for 4th year undergrads
and 1st year grad students, with little stats experience,
to learn this approach.

the suggestions was to test for heterogeneity. The snag, however, is that this
requires multiplying each cell value by its natural log. My data set has a lot
of zero values, which are important to keep; but of cours
