Hi, everyone here.
I am trying to get the training error of the model processed which can reveal how much the model fits the cases. The training error can reveal how many cases (from training set) are classified correctly. The lower traing error is, the more the model fits the training set. (Maybe overfitted) But I found it hard to get. I saw the life chart in AS 2005 which I am not quite understand and don't know how to code it in my program.
Is there some way to getting traing error or predicting error
I am now using this awful way to get the training error:
select t.*,CollegeTree.CollegePlans as pred
from collegetree
prediction join
openquery(DSource,'select * from CollegePlans') as t
on CollegeTree.StudentID = t.StudentID and
...
where t.CollegePlans = CollegeTree.CollegePlans;
and then use datareader.ItemCount to get the count of cases which classified correctly.
