Normal distributions arise throughout the subject of statistics, and one way to perform calculations with this type of distribution is to use a table of values known as the standard normal distribution table. Use this table in order to quickly calculate the probability of a value occurring below ...
The normal distribution is the best-known of the statistical distributions. It results in the familiar "bell-shaped" or Gaussian curve. In this chapter, we shall develop a relationship between the Gaussian distribution and the mean and standard deviation treated earlier. Once we know the ...

aIf we describe these people and events by using the normal distribution curve, people only paid attention to the "head" of the curve, rather than the " tail" of the curve 如果我们通过使用正常分配曲线描述这些人和事件,人们只支付了对“头的”注意曲线,而不是”尾巴"曲线[translate]...
The normal distribution is determined by the mean value and the standard deviation, representing the spread of values. The normal distribution is a key element to modern portfolio theory, a mathematical approach to investing that assumes that certain returns will follow a normal distribution. ...
Each correlation in the input matrix was estimated as a polychoric correlation between two categorical variables (Olsson, 1979), a polyserial correlation between a categorical and a continuous variable (Olsson et al., 1982), or a (standard) product–moment correlation between two continuous variables...
This paper offers a novel approach to formulate efficient ratio estimator of the population variance using a transformed auxiliary variable. The impact of transformation on auxiliary information has also been discussed. It is observed that incorporating a transformed auxiliary variable result in a high ...
(h) is still normally distributed due to the additivity of the normal distribution. To obtain the 1%-quantile of the normal distribution for the VaR calculation is not hard. We can then calculate VaR(1) or VaR(h) using (14). Under the Normal case, it is easy to find that the bias ...
