Description of equations used in estimating the peak timing
| Description | Equation | ||||
|---|---|---|---|---|---|
| Phase shift, Ψ as a distance of peak from beginning of time series in radians |
|
||||
| Variance of phase shift, Var(Ψ) |
|
||||
| Confidence interval of phase shift in radians |
|
||||
| Peak timing in months, where M is the length of one cycle |
|
||||
| Confidence interval for peak timing in months | Substitute equation 7 for Ψ in equation 8 |
