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?
Greetings from Novi Sad,
