R: no uniform distribution of errors for six 15-min periods. Higher error percentage in last 15-min: 1st 15-min= 7%| 2nd 15-min= 9%| 3rd 15-min= 12%| 4th 15 min= 17%| 5th 15-min= 9%| 6th 15-min= 23% AR: no uniform distribution of errors for six 15-min periods. Higher error percentage in last 15- min: 1st 15-min= 6%| 2nd 15-min= 10%| 3rd 15-min= 10%| 4th 15 min= 19%| 5th 15-min= 25%| 6th 15-min= 21% |
