Using Seasonality It is recommended that you keep all seasonality boxes checked on the RXForecast Options command dialog box. As long as Auto Seasonality is enabled, HP RXForecast will calculate seasonality and include it if the T-Probability of one parameter is greater than 90 percent. An important exception to this rule of thumb occurs when you use the Business Units trending method. As explained in "Seasonality and the Business Unit File" , when you use Business Units, you want to turn off any seasonality levels equal to or higher than the summarization implicit in the business unit file. Additionally, you might want to have seasonality disabled if you prefer looking at a forecast and discovering the seasonality for yourself.
