To apply the methodThe method calculates the log difference of neighboring series points for a certain period (ln(x[t]/X[t-N])):
dlog PoP. Previous period.
dlog YoY. Corresponding period of the previous year.
dlog YTD. End of the previous year.
It is included in the group of functions that perform transformations on series.
After the method is applied, in the workbook, based on each selected series a calculated series with a name of the dlog<Period>(<Series_Name>[t])(<Series_Name>) type is created, containing the calculation results. For example:
