Dear Peter

Thank you for your kind respons as well. You are right, we are in
constant debate whether it makes sense to remove variables (no matter
whether significant or not) from a total dataset which in itself has a
certain meaning and may not stand for other studies with differing
variables.

However, in biology it is common practice to remove non significant
factors (and sometimes also variables)from data sets (so called: forward
and backward elimination process), usually when they are permanently non
significant on all the paticular positions in the factor list.

Some authors suggest only to remove data which may have similar meanings,
and therefore may be understod as pseudorepliaions.

Best regards Knut
