What does FVU mean in UNCLASSIFIED
FVU stands for Fraction of Variance Unexplained. It is a measure of the variability in a set of data that is not explained by any model or prediction. It can be used to gauge how well a model fits the data and its predictive accuracy.

Essential Questions and Answers on Fraction of variance unexplained in "MISCELLANEOUS»UNFILED"
What does FVU stand for?
FVU stands for Fraction of Variance Unexplained.
Why is measuring FVU important?
Measuring FVU is important as it provides an indication of how well a model fits the data and its predictive accuracy.
Does higher or lower values indicate better performance?
Lower values indicate better performance, as they signify that the model explains more of the variance in the data.
How can I calculate FVU?
The formula to calculate FVU is 1 - (sum of squared residuals / total sum of squares). The sum of squared residuals represents the difference between what was predicted and what was actually observed, while the total sum of squares represents the total variation found in actual observations.
When should I use this metric?
This metric can be used when assessing any type of model, such as linear models, nonlinear models, and time series models. It should be used to determine how well a given model fits and predicts a particular set of data points.
Final Words:
In summary, FVU stands for fraction of variance unexplained which measures the variability in a given set of data that is not explained by any predictions or models made by researchers. Calculating this metric can be done using a simple formula and serves as an useful indicator to assess how accurately models fit data points and make valid predictions.
