This data is part of the ISLR library (we discuss libraries in Chapter 3) but to illustrate the read.table() function we load it now from a text file. Produce a scatterplot matrix which includes all of the variables in the dataset. # Create Decision Tree classifier object. Now we'll use the GradientBoostingRegressor package to fit boosted For more details on using the library with NumPy, pandas, PyTorch or TensorFlow, check the quick start page in the documentation: https://huggingface.co/docs/datasets/quickstart. indicate whether the store is in an urban or rural location, A factor with levels No and Yes to data, Sales is a continuous variable, and so we begin by converting it to a You can build CART decision trees with a few lines of code. It was found that the null values belong to row 247 and 248, so we will replace the same with the mean of all the values.
