hi,
I am quite new to the CART algorithm. I have classified some data using the 'classregtree' command. But i have one problem.
Now, once i submit a new data sample to a classification tree using 'eval' command, i get only the class name of that data, but i also want the probability of this classification. I want the value of probability by which each data sample belongs to a class. Is there any command which calculates this probability value.
Also i have to set a threshold value 't' to this probability 'p' so as to satisfy the following condition for a variable x
x=1 if p>t else x=0.
But i don't know how to chose this threshold value for my data. Its my final year project and i am running out of time so someone please help me out quickly.

----Thanks
