Couple days ago I was looking for well-known dataset – german credit. It is a good starter for practicing credit risk scoring. Unfourtuanetly I have found only original file in.data format without column names. Jan 09, 2019 German Credit Card (Source: VectorStock) Introduction of Exploratory Data Analysis (EDA) Exploratory Data Analysis refers to the critical process of performing initial investigations on data so as.
In our data science course, this morning, we’ve use random forrest to improve prediction on the German Credit Dataset. The dataset is

(etc). Let us convert categorical variables as factors,

Let us now create our training/calibration and validation/testing datasets, with proportion 1/3-2/3
The first model we can fit is a logistic regression, on selected covariates
Lucia maria mollin. Based on that model, it is possible to draw the ROC curve, and to compute the AUC (on ne validation dataset)
An alternative is to consider a logistic regression on all explanatory variables
We might overfit, here, and we should observe that on the ROC curve
There is a slight improvement here, compared with the previous model, where only five explanatory variables were considered.
Consider now some regression tree (on all covariates)
We can visualize the tree using
The ROC curve for that model is
As expected, a single has a lower performance, compared with a logistic regression. And a natural idea is to grow several trees using some boostrap procedure, and then to agregate those predictions.

Here this model is (slightly) better than the logistic regression. Actually, if we create many training/validation samples, and compare the AUC, we can observe that – on average – random forests perform better than logistic regressions,
