The standard normal distribution, Z is continuous and has a mean, median, and mode equal to 0. The standard deviation and variance are equal to 1. This variable is used to determine most of the probabilities. Answer and Explanation:1 ...
The Kolmogorov–Smirnov test can be modified to serve as a goodness of fit test. In the special case of testing for normality of the distribution, samples are standardized and compared with a standard normal distribution. This is equivalent to setting the mean and variance of the reference distr...
aFor a normal distribution, we could remove data points which are more than three standard deviations from the mean (since they have less than a 1% chance of belonging to the distribution). 为正常分配,我们可能取消是超过三标准偏差从手段的数据点 (,因为他们比属于的1%机会有发行的较少)。 [...
