I am very new to modelling techniques. I have couple of doubts:
1)If i perform a Hosmer lemeshow test to find the goodness of fit of the models, and the test fails. I meant to say that i got a really low p value. In such case what will i do to make sure that the hosmer lemeshow test doesnt fail?
- If the concordance is really low, how will i improve my concordance?
3)If in my confusion matrix, sensitivity and specificity is low. How will i increase it?
4)If i am looking at K-S statistics, and my max K-S is in later deciles ,lets say 8th or 9th . How will i improve it?
- If the rank ordering breaks, how will i correct it?
