Hiall,
If I have say 10 tables that i would like to wrap up in 1 view to
manipulate data inside these tables, do I then need 10 model.rb files

Ordinal response model
I have been asked to analyse some questionnaire data- which is not data I'm
that used to dealing with. I'm hoping that I can make use of the nabble
expertise (again).
The questionnaire has a section which contains a particular issue and then
questions which are related to this issue (and potentially to each other):
1) importance of the issue (7 ordinal categories from -3 to +3)
2) impact

Wine 1.00 the AppDB and State of the Winehq website.
In looking forward to the release of wine 1.0 I have a question about "Browse Applications by Rating"
http://appdb.winehq.org/browse_by_rating.php
When adding test data you can only add reports on what looks like the last 6 releases? Eg wine versions 0.956 / 0.957 /0.958 /0.959 /0.960
/0.961
Do these stat's on "Browse Applications by Rating" report this?

file and directory layout below app/models
Hiall,
Is it possible to organize my model files below app/models into
subfolders? E.g. I would like to put admin related models into their
own subfolder. This kind of structuring works for controllers and
views (scaffolding creates the right subfolder-model mappings), but
app/models always stays flat. I''d really like to be able to group my
code into logical, well packages :-) Yes, I

collection_select default selected value
Hiall,
Unfortunately I just can''t find out how to setup a default selected
value when using collection_select. My call is like so:
<%= collection_select(:consultant, :lastname, @consultants, :id,
:lastname, { :selected => @current_consultant.id } ) %>
which is not working, I debugged so far that I know that
@current_consultant.id contains the correct value.
Any tips?

piecewise linear regression
We sent questionnaires to lots of folks. The questionnaires
differed in word count (wc). For each questionnaire, I know wc
and whether the questionnaire was returned or not (status). It
looks like there is a fixed rate of return when wc is below a
break point, and the rate of return falls off linearly after
that.
I want to do a piecewise linear regression with two pieces

Relative strength of regression predictors (relaimpo vs. relimp)
Hello!
I am trying test my observed data against the null-hypothesis that
different items from a psychological questionnaire contribute equally to
the metric dependent variable that measures problems (sum score of a
questionnaire). That is, I am interested in relative strength of the
predictors.
Predictor items of the questionnaire are on a scale from 0-3, and
technically ordinal, although most
