What to do?

1. Open the zip file with the CSV tables. Inspect the tables using your favorite tool (it can be excel, a library, a programming language etc).
2. Describe the data contained in the tables:
• For the categorical variables, compute frequencies
• For the numerical variables, compute min, max, mean, median, standard deviation etc
• Repeat the description after separating upgrades from non-upgrades
• Plot visualization graphs for variables. For example, boxplots for numerical variables and histograms for categorical variables
3. Rule induction (modeling):
• Open cplint and select the

  bc_train

  file
• Inspect the file
• Run

  induce(X).

  on the query panel
• Add expert rules to

  bc_train

  , including the modeb and determination predicates, and learn some new rules
