- SEASONAL INDEX FOR A TIME SERIES
-
- MOST BUSINESSES SHOW SEASONAL VARIATIONS OF SALES. THAT MEANS
- THAT THE SALES AT ONE TIME OF THE YEAR ARE HIGHER THAN THOSE
- AT OTHER TIMES YEAR AFTER YEAR. THE SEASONAL INDEX FOR A
- SEASON(OR MONTH) IS THE PERCENTAGE THAT SEASON'S SALES ARE OF
- THE SALES IN AN 'AVERAGE' SEASON. FOR EXAMPLE IF A STORE SELLS
- $60,00 PER YEAR, OR $5,000 PER MONTH AND AVERAGES $8,000
- DURING JUNE THEN THE INDEX FOR JUNE IS 160.
-
- THIS PROGRAM WILL COMPUTE SEASONAL INDICES. WHAT IS
- NECESARY IS THE INPUT OF SALES AMOUNTS FOR EACH SEASON FOR
- AT LEAST SEVERAL YEARS. THE PROGRAM WILL ACCEPT FEWER YEARS
- BUT THE RESULTS WOULD BE MEANINGLESS.
