Table 1 Definition of Standard Classification Statistics.
From: Translating large-scale climate variability into crop production forecast in Europe
Standard Classification Statistics | Definition | Abbreviation | Formula |
|---|---|---|---|
Hit Rate | Probability of a “True Low Production” (TL) over the total samples of “Low production” (LP). | HR | \((\frac{TL}{LP})\times 100\) |
Correct Rejections Rate | Probability of a “True High Production” (TH) over the total samples of “High Production” (HP) | CR | \((\frac{TH}{HP})\times 100\) |
False Alarm Rate | Probability of a false “Low Production” | FAR | 1−CR |
Miss Rate | Probability of a false “High Production” | MS | 1−HR |
Positive Predictive Value | Probability of a “True Low Production” over all “Low Production” | PPV | \(\frac{{\rm{HR}}}{{\rm{HR}}+{\rm{FAR}}}\) |
Negative Predictive Value | Probability of a “True High Production” over all “High Production” | NPV | \(\frac{{\rm{CR}}}{{\rm{CR}}+{\rm{MS}}}\) |
Balanced Accuracy | Average of Hit Rate and Correct Rejection | BACC | \({\rm{HR}}\times 0,5+{\rm{CR}}\times 0,5\) |
