I am performing Decile analysis on the dataset where i have to figure out defaulters.
in Default column we can see that defaulter are not in decreasing order across the decile
(e.g. 27 -> 28 and 14 > 18 )
what can be the possible reason for this ?
- Dataset does not have missing value .
- for outliers i have done capping using ( mean ± 3*SD)
- i have reduced the variable using PCA.
- most of the variable are categorical variable for which i have created dummy variable
Please guide me in order to correct this .
