Hi all,

I've attached the notes from Mohammed's & my online chat re validation &
methodology. The main points discussed were:
1. Distinguish between (i) academics' and (ii) consultants' use of
validation & methodology. Former through peer review, being seen to do =
the
work 'the right way'; latter through whether it gives the right results =
or
not. The overriding aims of (i) is to try to have a "basic" =
understanding
about such varied topics as the economy, modes of social interactions,
population dynamics, computational anthropology, etc.. while on (ii) is =
has
more to do with trying to make better decisions that will have a direct
effect on the bottom over some limited time horizon.=20
2. Misuse of ABMs:=20
* the misinterpratetion of many-to-one problems (in particular, when
attempting to induce (micro) rules from observed (macro) behaviour;=20
* Over claiming predictive abilities (clients expecting quantitiative
predictions and getting qualitative ones).=20
* Very limited attempts at validation with the real world.=20
3. Proper use of ABMs: at least one proper use (both our experience) is
starting from (micro) rules and assumptions and generating the (macro)
behaviour that they imply. This deductive process is one-to-one in =
contrast
to the inductive many-to-one. A great deal of value of ABM to the =
business
world is in helping them understand more about the fallacy/veracity of =
their
assumptions. This in itself would help them make better decisions =
without
claims of predictive accuracy.=20
4. How to proceed:=20
* Ultimately, funding is needed=20
* Involvement of credible parties (SFI/BizNet?) (probably not the
established consultancies - either (i) already have their own approach =
or
(ii) would be embarassed to admit to clients that they didn't.=20
* Assemble a 'version 0.1' framrework - a brain-dump of as many
practitioners' approaches as practical.=20
5. Actions:=20
* RH to explore SFI/BizNet aspect
* Both to carry out their brain-dumps, try and get others to do same
and attempt to incorporate. (If anyone has any ideas about how to do =
this,
please pitch in).
