Chapter 2: Manipulating data with Breeze

This chapter introduces manipulating tabular data with Breeze. We use CSVs with the true and self-reported heights and weights for 181 men and women as an example dataset.

• HWData.scala: helper routines for loading the height-weight data from CSVs.
• LogisticRegression.scala: Re-usable Scala class implementing logistic regression.
• LogisticRegressionDemo.scala: Example run for the Logistic regression class.

Type $ sbt run to run LogisticRegressionDemo. Type $ sbt console to get a Scala console pre-loaded with Breeze. Type $ sbt assembly to get a fat jar containing all the dependencies.
