Introduction

This project shows and explains the analysis of the AIDA dataset, which aims at a business failure prediction, risk factors exploration, and distributions investigation.

Question A

• Compare the distributions of size and age between failed and active companies at a specific year
• Do they change for a specific company form?
• Do they change for a specific sector?

Question B

• Compare the distributions of size and age of failed companies over different years
• Do they change for a specific company form?
• Do they change for a specific location?

Question C

• What is the probability of failures conditional to size/age of firms at a specific year?
• Does it change for a specific company form?
• Does it change for a specific sector?
• Does it change for a specific location?

Question D

• Fit a parametric model

Question E

• Extend the model with a selective classification
