Dialog box items

Title: To replace the default title with your own custom title, type the desired text in this box.

First obs. is in seasonal period: By default this value is 1 because Minitab assumes that the first data value in the series corresponds to the first seasonal period. Enter a different number to specify a different starting value. For example, if you have monthly data and the first observation is in June, then enter 6 to set the seasonal period correctly.
