How to Calculate MSR in Python
MSR stands for Mean Squared Residuals. MSR can be used to compare the the difference between estimated Y and observed Y in model. It is ratio between Sum Squared Residuals and the number of observations, i.e., n. The following is...

Difference between MSD and MSE
MSD stands for Mean Squared Deviation, whereas MSE stands for Mean Squared Error. Quite often, you will find that they are synonymic. Both MSD and MSE can be used to compare estimated values and observed values in a model. The...
