We have fun with one-very hot security and get_dummies toward categorical variables into the application studies. On nan-thinking, we have fun with Ycimpute library and you will expect nan viewpoints from inside the numerical variables . To have outliers investigation, i pertain Local Outlier Grounds (LOF) to the software research. LOF detects and you may surpress outliers data.
For every single newest financing on app research may have several early in the day fund. For each and every past app provides one to row and that is identified by this new element SK_ID_PREV.
I’ve each other float and you may categorical variables. I implement score_dummies to possess categorical details and you will aggregate to help you (mean, min, maximum, matter, and you may sum) to have drift parameters.
The data regarding percentage records getting previous money at home Credit. Discover one line for each produced percentage and something row for each overlooked fee.
According to the forgotten worth analyses, shed opinions are incredibly small. So we won’t need to simply take any step getting missing values. I’ve one another drift and you may categorical parameters. I incorporate get_dummies for categorical details and aggregate so you can (mean, min, max, count, and you may contribution) for float details.
This info include monthly equilibrium snapshots away from previous credit cards that the fresh candidate acquired from home Borrowing
