Python How do you convert categorical data to numerical data in Pandas? This can be done using get_dummies() and replace methods. How do you convert categorical data to numerical data in Scikit-learn? This can be done using label encoding and one-hot encoding. ...
While the import statements in the first cell probably look familiar from your experience of using python in the command line or in a script, the%matplotlibinline command is not actually python: it is a markup instruction to the notebook thatmatplotlibimages are to be displayed inline the brows...
we focused on cases where the main relationship was between two numerical variables. If one of the main variables is “categorical” (divided into discrete groups) it may be helpful to use a more specialized approach
