Julia for Data Science (Video 24)

The video tutorial explains how to train and test a decision tree model using a data set. It covers dividing the data into training and testing sets, constructing the model, and evaluating its performance through predictions and statistical measures like correlation and R squared values. The tutorial also discusses pruning the model to remove outliers and using cross-validation for accuracy. The video concludes with a brief introduction to applying a generalized linear model for regression analysis in the next session.
