a) Pre-processing: Check the data to see if there is any missing value. The simplest approach to deal with the missing values is to remove the rows with any missing values. Use are free to pick other methods from literature to deal with missing data.t the final data provided to the regression models should not have any missing value. Also, make sure that the variables have the correct type. For example, "station" number doesn't really have a numerical meaning! Or the date should not be included as a predictor.
