Webb10 aug. 2024 · What is a good MSE value? The closer your MSE value is to 0, the more accurate your model is. However, there is no 'good' value for MSE. It is an absolute value which is unique to each dataset and can only be used to say whether the model has become more or less accurate than a previous run. http://gauss.stat.su.se/gu/mm/SAS_PROC_MIXED.pdf
