>> X = timetable2table(T); % regressionLearner perfers to have tables.

X.NumericDate = datenum(X.Date); % add the date as a numeric value

% remove the missing year of data (2016)

X = rmmissing(X);

% Use this command to open the regression learner app and train a coarse

% tree:

% regressionLearner

% this is the model saved by generating code from the app:

[trainedModel, validationRMSE] = trainRegressionModel(X)
