The basic set of Model Validation metrics against certain dataset (could be the Training dataset or Validation dataset).
There is no complete set of numbers to define the Goodness of fit and different studies may use different sets of Goodness of fit metrics.
The most widely used set in engineering practice is summarized in the table below:
|Root Mean Square Deviation (RMSD)||RMSD|
|Average Absolute Relative Error (AARE)||AARE|
|Maximum Absolute Relative Error (MAXARE)||MAXARE|
|Coefficient of determination (R2)||R2|
|Pearson correlation coefficient (ρP)||ρP|
