Hi Jun (& al),
Susan and I used the new Ranker to assist in making our
decisions while doing male ranks this week. We found some interesting
things. When comparing new ranker to Tabby's ranks she sent us from
FoxPro ranker, there were discrepencies in actual agonistic
interactions. After doing some looking within babase, it seems that the
new ranker is 'creating' data that don't exist within babase. I have
included some specific examples so that we can try to figure out where
these anomalous data are being generated from. They were almost all
interactions between subadults, and some of them were even symmetrical,
and would have cancelled each other out essentially... but we need to
figure out what's causing this to happen. Also, lastly... we found that
when we selected 'ALM' the same group of individuals was produced as was
produced when we selected 'ADM'. In other words, infants, juveniles and
subadults are being selected when we select the ''ADM" ranktype. Why is
this?
Anomalous Interactions: None of these interactions can be found in babase
1. Viola's Group June 2005 SEB>VIB and EGO>SEB. , (but there was one
listed for VIB>SEB (which makes a lot more sense))
2. Viola's Group Aug 2005 VEB>LOF x1 and YOK>LOF x1
3.Viola's Group Sep 2005 THR>NJU and VEB>WES
4. Linda's Group Nov 2005 LES > MOR and LES > LAW
These are all of the specifics I am coming across for now, but if we
need to look into it more deeply to find the root of the problem, I can
regenerate the matrices and compare them with Tabby's to find more examples.
Cheers
Lacey
