The MsLvlMethod enumeration contains transformations used by the Level function.
It is used by the following method:
Value | Brief description |
0 | Pch. Percent change to the previous period: (X[t]/X[t-1]-1)*100. |
1 | PchY. Percent change to the corresponding period (F) of the previous year: (X[t]/X[t-N*F]-1)*100. |
2 | PchA. Percent change to the previous period with the seasonal adjustment (S): ((X[t]/X[t-1])S-1)*100. |
3 | Diff. Series rate of change to the previous period: X[t]-X[t-1]. |
4 | DiffY. Series rate of change to the previous period (F) of the previous year: X[t]-X[t-N*F]. |
5 | Log. Natural logarithm: ln(X[t]). |
6 | DLog. Logarithms difference: ln(X[t]/X[t-N]). |
