Hi,
I am a student in Bar Ilan University ,and new into ALGLIB .
I am trying to create a DecisionForest using ALGLIB C#.
My input is excel file with the following values ( Extension , Department , Sex , Country_of_Birth , Birth_Date , Pishco , Cumulative_Average , Cerdit_Sign , Credit_Overoll , Ptor , School_Year , Total_Years , Residence , Population_number , region , status )
number of rows in the excel file is :1000
The data was divided to 700 records for training and 300 records for testing.
the training set was allocated into 2D double array
The "status" is the value to be predicted
I have two questions:
1.how can I specify the "status" field as the value I would like to predict ?
2.What is the value that I need to insert into NPoints field ?

Thanks,
Michael Bini
