While I was taking the credit risk modeling course and we calculated scorecard from p-values, I noticed one discrepancy in the
the given formula and the formula used in the tutorial notebook:

# Formula Used in the tutorial notebook coding

df_scorecard['Score - Calculation'][0] = ( 
( df_scorecard['Coefficients'][0]
- min_sum_coef
) 
/ 
(max_sum_coef - min_sum_coef)
) * (max_score - min_score) + min_score

# Formula image given in course

df_scorecard['Score - Calculation'][0] = ( 
( df_scorecard['Coefficients'][0]
- min_score
) 
/ 
(max_sum_coef - min_sum_coef)
) * (max_score - min_score) + min_score

# Great Problem: None of the formulae works for different features

I was trying different set of features to calculate the scorecard for the same problem using the exact notebook.

But I was greeted with wrong range of scorecard.

I was expecting range between 300 and 850, but the final output was different.

For the easiness of debugging the problem I have shared the notebook in Gcolab.

In this notebook I have different features and different p-values.

My aim is to get the scores from p-values.

When I followed the method provided in the course I got values out of range.

HOW TO GET THE VALUES WITHING THE RANGE?

Thanks a lot.
