控制图判断规则的概率计算，请高手指点

在Minitab中对控制图有判断规则，实际上这都是些小概率事件，请高手指点一下，每条规则用概率统计时，怎么计算，特别是其中关于连续6点交互上升下降这一条，请高手指点，或发个关于这方面的文章，谢谢了！
1 point more than 3 standard deviations from center line

9 points in a row on same side of center line

6 points in a row, all increasing or all decreasing 特别是这条，请高手一定要指点呀！！

14 points in a row, alternating up and down

2 out of 3 points > 2 standard deviations from center line (same side)

4 out of 5 points > 1 standard deviation from center line (same side)

15 points in a row within 1 standard deviation of center line (either side)

8 points in a row > 1 standard deviation from center line (either side)
