This dataset contains 64 financial indicators of over 10000 companies. Column 'class' is, instead, binary and indicates whether the company went bankrupt within a certain period after the indicators were collected.

You are expected to:

• Perform data exploration, cleaning, imputation.
• Use data visualisation techniques to explore the data set.
• Come up with (binary) classification models to predict whether a company will be bankrupt.
• Perform model selection among these models, with a rigorous methodology.
• Report you results clearly and concisely.
