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

For such cases, we need to extend the normal distribution, and in particular the variance, in scalar/matrix form. In the vector form of the normal distribution, the variance V becomes a matrix, ...

Learning outcomes On watching this video, students should be able to: Explain why the normal distribution is so important for statistics. Explain that the central limit theorem (CLT) is about the ...

The logistic transformation applied to a d-dimensional normal distribution produces a distribution over the d-dimensional simplex which can sensibly be termed a logistic-normal distribution. Such ...

The central limit theorem (CLT) states that the distribution of a random variable in a sample will begin to approach a normal distribution as the sample size becomes larger, regardless of the true ...
