Intro to Time Series
Mean Squared Error (MSE) is a statistical measure that evaluates the average of the squares of the errors, which are the differences between predicted and actual values. It serves as a key metric in assessing the accuracy of forecasting models, indicating how well a model can predict outcomes. A lower MSE value implies a better fit of the model to the data, making it an important concept in time series analysis and financial modeling.
