The standard normal distribution (z distribution) is a normal distribution with a mean of 0 and a standard deviation of 1. Any point (x) from a normal distribution can be converted to the standard normal distribution (z) with the formula z = (x-mean) / standard deviation. z for any pa...

标准常态分布StandardNormalDistribution 在隨機實驗中,所觀察的隨機變數,如:人的身高、體重、家庭所得、地區的氣溫、股票的價格、工人的工資、醫生看病的時間,都是連續的隨機變數。這些連續隨機變數具有共同的特性,其機率分配的形態頗為類似,比如人的身高,大部份的人都很接近,而且集中在平均身高左右,只有少部份...

正态分布是一个双参数(均值和标准差)曲线族。中心极限定理说明,当样本大小趋向无穷时,任何分布的各独立样本的总和服从正态分布。 2.标准正态分布 标准正态分布是比较特殊的正态分布,即期望值μ=0,即曲线图象对称轴为Y轴,标准差σ=1条件下的正态分布,记为N(0,1)。
Two factors determine the characteristics of the distribution; which are mean {eq}(\mu) {/eq} and standard deviation {eq}(\sigma) {/eq}. These are effectively the most likely outcome and how likely it is for a result to deviate from that outcome. In general, the normal distribution is...
The standard normal distribution is the only normal distribution we really need. Why? Well, we can use a normal distribution to look up a probability for xx if xx is normally distributed and we know its population mean μ and we know its population standard deviation σ. With these 3 numb...
正态分布,又称高斯分布(),是一种重要的概率分布,是由数学王子高斯 [^4] 在 19 世纪初提出的。有很多日常现象都符合这种分布,如人的身高、考试成绩等。正因为它几乎无处不在,所以叫 Normal Distribution 。德国曾经发行的一款 10 马克的纸币上就印着...
