# 1. Class September 8, 2022 (Lab session) First steps: * Read the data; * Separate oberservations from *targets* (wtf does this mean); (I think he just means the indep. vars. and the dep. var) * Split the data in two: **training** and **testing** sets. The first thing we are going to do with this dataset is to split it between a traning and testing sets. This will allow us to fit the model and also avoid overfitting. # 1. Loading data 1. Read data (from file, database) 2. Separate observations from *targets* 3. Divide data into two sets: **training** and **test**
