Hi ,

 

Can anyone pelase help me with following question I am trying to solve:

Description of my problem:

I have the following "target variable": 1: Growth 2. Stable 3. Decay. 

The distribution of each is:

1. Growth=4%

2.Stable=88%

3.Decay=8%

 

Since, this is situation of imbalance target rate I have taken 10% of the stable to model.

Now I have the model results and the confusion matrix.

 

Issue:

When I try to try back the complete sample, I see the values of predicted probabilities get disturbed.

Can anyone please suggest how to score the complete sample in ordinal regression when we model only a sample of it.

How are you scoring your dataset? 

Have you considered a prior probability instead of reducing event rate? 

 

Otherwise, perhaps this is helpful
