WebMay 23, 2024 · 2. Mean Square Error(MSE)/Root Mean Square Error(RMSE) 3. Mean Absolute Error(MAE) R Square/Adjusted R Square. R Square measures how much variability in dependent variable can be explained by the model. It is the square of the Correlation Coefficient(R) and that is why it is called R Square. WebWell, we average 2 / (1/10 + 1/20) = 13.3 gigabytes/dollar for each part. That is, we could swap the client & server for two machines that cost 13.3 gb/dollar. Because data is both sent and received (each part doing “half the job”), our true rate is 13.3 / 2 = 6.65 gb/dollar.
