If a linear regression model is used for prediction, the mean squared error of prediction (MSEP) measures the performance of the model. The MSEP is a function of unknown parameters and good estimates of it are of interest. This article derives a best unbiased estimator and a minimum MSE esti...
I know the log function is undefined for negative values and that mean squared log error uses this formula: This means the problem must lie with y hat i.e. after fitting the linear regression predicts a negative value, but this isn't the case: ...
I am comparing the mean squared error (MSE) from a standard OLS regression with the MSE from a ridge regression. I find the OLS-MSE to be smaller than the ridge-MSE. I doubt that this is correct. Can anyone help me finding the mistake? In order to understand the mechanics, I am not...
