Exported regression learner model. Where to find the training results - RMSE, R^2, MSE, MAE?

I am unable to find the values mentioned in the title, what path would I have to follow in the model struct to find them?

I notice there are several sigma values scattered around the struct, however I am unsure what they stand for? Just standard deviation?

Same applies to Alpha, Beta and Gamma values, but I think they are just shape parameters.
