Checking for correlated features
You'll now return to the wine dataset, which consists of continuous, numerical features. Run Pearson's correlation coefficient on the dataset to determine which columns are good candidates for eliminating. Then, remove those columns from the DataFrame.

Oefeninstructies
- Print out the Pearson correlation coefficients for each pair of features in the
winedataset. - Drop any columns from
winethat have a correlation coefficient above 0.75 with at least two other columns.
