What is the MPG in Random Forest Regression ?

t = templateTree('NumVariablesToSample','all',...

'PredictorSelection','interaction-curvature','Surrogate','on');

rng(1); % For reproducibility

Mdl = fitrensemble(Z,MPG,'Method','Bag','NumLearningCycles',200, ...

'Learners',t);

What is the MPG in above code?

Please let me know.

Thanks.

That code looks similar to example code from the documentation for fitrensemble or templateTree.

In those examples, MPG is one of the variables in the data table. (In your code Z would be that table.) It's the miles per gallon for cars in the example carsmall dataset.

MPG should have quotes around it, in general.

Mdl = fitrensemble(Z,'MPG', ...
