Discover what a log-normal distribution is, its financial applications, and how to calculate it, including using Excel for ...

Normal or bell curve distribution can be used in portfolio theory to help portfolio managers maximize return and minimize risk.

The sets of probabilities in Equations 2 and 3 are called probability distribution functions . For these two cases, the functions are discrete, having values only at the integer mesh points.

The function can be used to calculate all moments. For instance, a function with modulus or peak value, standard deviation, and mean of the distribution as parameters requires three moments for ...

The agreement between the empirical and the normal distribution functions in Output 2.1.1 is evidence that the normal distribution is an appropriate model for the distribution of breaking strengths.

An algorithm involving polynomial approximations for evaluation of the normal distribution function is presented which may be implemented in fast and accurate computer programs of moderate length.

SAS/INSIGHT software provides tests for the null hypothesis that the input data values are a random sample from a normal distribution. These test statistics include the Shapiro-Wilk statistic (W) and ...
