Moving average "S" to "Y" as shown above, though other techniques exist, such as setting "S" to an average of the first 4 or 5 observations. The importance of the "S" initialisations effect on the resultant moving average depends on "α"; smaller "α" values make the choice of "S" relatively more important than larger "α" values, since a higher "α" discounts older observations faster. Whatever is done for "S" it assumes something about values prior to the available data and is necessarily in error. In view of this, the early results should be regarded as unreliable until the iterations have had time
