Dear Rooters,

I am a very new user of RooFit package. I am trying to create a toy montelcarlo with following steps:

1_ Create a background model : RooAddPdf 
2_ Create a signal model : RooAddPdf
3_ Create signal+background.
4_ Generate Date : RooDataSet.

So far it is fine now I need to do following:

5_ Go to each data entry stored in RooDataSet object so created.
6_ Calculate the value of Signal PDF at that data point.
7_ Cakulate the value of BackGrnd PDF at that data point.
8_ Print out following text table : (Each row corresponding to a generated event)

   dataPoint : sigPDF : bakPDF

Can amyone help me with steps 5, 6,7 ??
