How to create a multi-condition derive node?

Hi:

   In the Clementine, Derive Conditional nodes use If-Then-Else statements to derive the value of the new field. How to create a multi-conditions( if-then elseif-then elseif then... else) Derive node?  for example, the origin field is "age".  I want to modify the abnormal values and keep the normal values for that the abnormal values are "dirty".

       If the Age <=  0 then Age =0

       elseif Age >=120 then Age = 120

       else Age= Origin Age

    I try many times in the Derive node ,but there always something wrong. How to create such Node?

    Thanks in advance!

connecting to dtatbase via scripting

hi

is it possible to script to connect to a database? Our DB2P connection times out after 10 mins and icks me out. By the time I have run one section of the stream the database nodes are no longer connected and the stream stops. I have tried to re-create the Database nodes using script or use a small dummy database connection to keep the connectino alive but neither work.

 can the database connection be scripted?

 thanks

SPSS Clementine newbie..any help is much appreciated!

Hi!

I am in the progress of researching/writing for my master thesis at the university from the topic of Data Mining for CRM. This topic is still quite new from where I come from (Serbia) so I have no real support or to say on-hand help to guide me with it. I was recommended using SPSS Clementine for this project. I have version 8.1 to use.

Actually as I have no data sets available from companies I was wondering if someone could guide me on building a simple model (nothing too fancy) , to select which modelling techniques should I use to solve my business problem, what data do I need in which format etc. So nothing too complicated, just to help get me started, as I find the demos unappealing and the tutorials not really helpful.

I am a smart kid (Mensa member since 2001) but your guidance could shorten my learning-curve by ages! 

 Anyone up for that?
