C5.0

[E. Bernardo]

I am studying decision tree models using clementine 12, particularly the C5.0.  Does anyone know how the C5.0 selects the predictor variables; and how it perform splits?

 

I would appreciate if you could direct me to an online article.  I have tried to use my browser unluckily I was not successful.

 

Thank you.

Dear all,

I read in Field "Discovering Statistic Using Spss" that the outcome variable of a regression should be unbounded. Despite that I've seen regression ran on five or seven points scales...Could you help me understand "how wrong" it is to run regression on bounded scales?

Thank you very much,

Best regards,

Jean-Philippe

Hi Pang,

If you want to save your data in Excel with variable values you can do the following: File ... Save as... At type select: Excel .... and tick: "Save value labels where defined instead of data values"

   OR:
SAVE TRANSLATE OUTFILE='D:\Work\NAME.xls'
  /TYPE=XLS /VERSION=8 /MAP /REPLACE /FIELDNAMES
  /CELLS=LABELS .


If you need only the value labels: File... Display data file information -> Working file   - than export the output in Excel.


Regards,
Beata

It uses an entropy method.

 

You might want to start by taking a look at the literature out there on c4.5.

 

http://en.wikipedia.org/wiki/C4.5_algorithm

 

There tends to be more out there about c4.5 which was the pre-cursor to c5

 

Hope this helps
