PySpark - Normalize (Standardize) train and test dataframes: [ (x - mean) / std_dev ]
# Based on the solution here: https://stackoverflow.com/questions/44580644/subtract-mean-from-pyspark-dataframe
# Function to normalise (standardise) PySpark dataframes
def standardize_train_test_data(train_df, test_df, columns):
'''
Add normalised columns to the input dataframe.
formula = [(X - mean) / std_dev]
Inputs : training dataframe, list of column name strings to be normalised
Returns : dataframe with new normalised columns, averages and std deviation dataframes
