There are a lot of error metrics for regression evaluation.

RMSE,MSE,MAPE,NRMSE,MAE, etc…

Which one to chose when and what is the best threshold value.

Thanks in advance

Hi @raviteja1993,

Selecting an evaluation metric can be a tricky task but there are no set of rules to define which metric to use when. For a general segregation, we can say that RMSE and MSE can be used for regression problem while MAPE would be used with recommendation system problems.
