5.5 Mean Squared Error (MSE) Similar to MAE, mean squared error is another metric used in regression-based sentiment analysis tasks. It calculates the average squared difference between the predicted sentiment
We consider this problem in a regression framework by considering a ridge logistic regression (RR) with three alternative ways of shrinking the estimates of the event probabilities. While it is shown that all three variants reduce the mean squared error (MSE) of the MLE, there is at the same...
mean squared error (MSE), the average squared difference between the value observed in a statistical study and the values predicted from a model. When comparing observations with predicted values, it is necessary to square the differences as some data values will be greater than the prediction (...
Notice that the numerator is the sum of the squared errors (SSE), whichlinear regressionminimizes. MSE simply divides the SSE by thesample size. Learn more aboutSum of Squares: Definition, Formula & Types. Interpreting the Mean Squared Error The MSE is the average squared distance between the ...

This article mainly aims to study the superiority of the notion of linearized ridge regression estimator (LRRE) under the mean squared error criterion in a linear regression model. Firstly, we derive uniform lower bound of MSE for the class of the generalized shrinkage estimator (GSE), based on...
