De-seasonalizing a time series involves removing the seasonal component (S) from the data. This is done by dividing the original series (which is the product of Trend (T), Cycle (C), Seasonality (S), and Irregular (I) components) by the seasonal component (S), resulting in $T \cdot C \cdot I$, which removes the seasonal effects.

Which of the Following Equations De-Seasonalize a Time Series? A) (T⋅C⋅S⋅I)/T=C⋅S⋅I( \mathrm { T } \cdot \mathrm { C } \cdot \mathrm { S } \cdot \mathrm { I } ) / \mathrm { T } = \mathrm { C } \cdot \mathrm { S } \cdot \mathrm { I }(T⋅C⋅S⋅I)/T=C⋅S⋅I
