WebTo measure the performance of your regression model, some statistical metrics are used. Here we will discuss four of the most popular metrics. They are-Mean Absolute Error(MAE) Root Mean Square Error(RMSE) Coefficient of determination or R2. Adjusted R2. Mean Absolute Error(MAE) This is the simplest of all the metrics. 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.
