The Pattern column is used to invoke the pattern mode where the model will repeat a given pattern (as opposed to Override mode). Valid entries include:
Monthly - When a monthly pattern is entered, the model stores the specified value for each month. In subsequent months where a value is not specifically entered, the model will use the stored value. In this way, a set of 12 records can specify a monthly pattern throughout time.
Daily - The daily pattern will use the specified value for each day of the month throughout the study.
Hourly - The hourly pattern will use a given 24 hour pattern throughout the study.
