Hi,
Perhaps is a silly question, but is my first time working with ANOVA
and I don't understand the meaning of the output of ANOVA function in
OCTAVE.
I'm running ANOVA test on some data and I have the following results...
What is the meaning of p-value ??? Is Octave taking 95% of confidence,
or 97.5% ? What if p-value is greater or equal to 1 ???
Thanks
Drake.
Here are some results....
