Resolution

Resolution

The default value is "Regular" and you can select between "Regular" and "High".

When "Regular" is selected for the Resolution parameter, the spectrum analysis routines will only search for integral cycles in the data (e.g., cycles that are whole numbers such as 6, 10, 14, etc.). When "High" is selected, the spectrum analysis routines will search for fractional cycles (e.g., 7.20, 10.393, etc.). The "Regular" option is faster than the "High" option in terms of the time required to complete the calculations. The "High" option, however, tends to be more accurate since cycles in fnancial time series are often fractional.

Note that, for text display purposes when "High" is selected, all fractional cycles are rounded to the nearest quarter-cycle.
