[R] R: Re: Differences in output of lme() when introducing interactions

[John Maindonald]

Do you have legal advice that suing the University (if that is the right context)
would actually be a fruitful way forwards, that it would achieve anything
useful within reasonable time and without causing the student severe
financial risk?

What may work in that context is for students to collectively complain that
important aspects of their training and support are being neglected.
With the rapidity of recent technological change, the issue is widespread.
To an extent, able post-docs and PhDs have to lead the charge in getting
training and support updated and brought into the modern world.

Dear Angelo

I suggest you do an online search for marginality which may help to
explain the relationship between main effects and interactions. As I
said in my original email this is a complicated subject which we are not
going to retype for you.

If you are doing this as a student I suggest you sue your university for
failing to train you appropriately and if it is part of your employment
I suggest you find a better employer.

Dear Bert,
thank you for your feedback. Can you please provide some references
online so I can improve "my ignorance"?
Anyways, please notice that it is not true that I do not know statistics
and regressions at all, and I am strongly
convinced that my question can be of interest for some one else in the
future.

This is what forums serve for, isn't it? This is why people help each
other, isn't it?

Moreover, don't you think that I would not have asked to this R forum if
I had the possibility to ask or pay a statician?
Don't you think I have done already my best to study and learn before
posting this message? Trust me, I have read different
online tutorials on lme and lmer, and I am confident that I have got the
basic concepts. Still I have not found the answer
to solve my problem, so if you know the answer can you please give me
some suggestions that can help me?

I do not have a book where to learn and unfortunately I have to analyze
the results soon. Any help? Any online reference to-the-point
that can help me in solving this problem?

Thank you in advance

Best regards

Angelo
