WebA forecaster might calculate MSE values on just the most recent data in the time series data set because a.the MSE will decrease with newer data. b.a model built on older data is likely inaccurate. c.forecasting models always need updating. d.they might be interested in how well the forecasting method performs on the more recent data. WebWhile the approach detailed above (computing MSE at various values of \(\hat\theta\)) quickly got us to a good estimate, it still relied on evaluating the MSE value across a grid of hand-specified values. If we didn’t pick a good range to begin with, or with enough granularity, we might miss the best possible estimator.
