[機統] 機率分布的相關問題
目前在看一篇論文
他有一章節有提到機率分布的內容
可是我不是很懂它的意思 所以上來問問
N is the total number of the disturbers(干擾者).
It follows a normal distribution with standard with
A.σ=5.47 μ=0.88 for frequencies = 0-10MHz
B.σ=3.94 μ=0.35 for frequencies = 10-20MHz
In order to find the number of disturbers in A and B. We have following step:
1) Produce a large number of normally distributed numbers (i.e., 10000) with
the equivalent characteristics for the mean value and standard deviation.
2) Discard the negative values
3) Take the mean value, which is the number of disturbers.
上面是我從文章中節錄下來精簡過的內容
我所知的常態分佈就是跟面積相關的
多少標準差內機率多少 這樣而已
可是不知道的是它的x,y軸各表示甚麼
再加上上面論文的內容又提到個數及頻率
我就不知道怎麼跟常態分佈搭在一起
內容有點多
還請多多幫忙
感謝
