Table 1 Relative growth classification on day \(j\)
\({\boldsymbol z}_{\mathbf j}\) values | Relative growth on day \(\boldsymbol j\) |
|---|---|
\({z}_{j}>{P}_{80}\) | Rapid growth |
\({P}_{60}<{z}_{j}\le {P}_{80}\) | Growth |
\({P}_{40}<{z}_{j}\le {P}_{60}\) | Stability |
\({P}_{20}<{z}_{j}\le {P}_{40}\) | Reduction |
\({z}_{j}\le {P}_{20}\) | Rapid reduction |
