  "id": "MLC-T-CHM-010404",
  "term": "Root mean squared error of prediction",
  "field": "Chemistry",
  "definition": "A measure of the average magnitude of the errors in predictions made by a model on a set of new, unseen data. It quantifies the difference between predicted values and actual values, providing an indication of the model's predictive accuracy. A lower RMSEP value indicates a more accurate predictive model.",
