Continuing with the analysis of Big Rig, Rains asks his students to calculate the mean squared error(MSE). Assume that the sum of squared errors (SSE) for the regression model is 359.A. 21.118.B. 17.956.C. 18.896. 正确答案:A 分享到: 答案解析: The MSE is calculated as SSE / (n ...
TheMean Squared Error (MSE)is an estimate that measures the average squared difference between the estimated values and the actual values of a data distribution. In regression analysis, the MSE calculates the average squared differences between the points and the regression line. That is, the mean...
Example 1 has explained how to compute the MSE using the mean function and the residuals of our model. However, the R programming languages provides alternative ways to calculate the mean squared error. This example illustrates how to use the mean and predict functions to calculate the MSE of ...
using software. However, the curve will not match your data points exactly, and when it doesn't, you may wish to calculate the root mean squared error (RMSE), in order to gauge the extent to which your data points vary from your curve. For each data point, the RMSE...
