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

In this column, we're going to look noise in the eye, and deal with its nature. We'll discuss the behavior of random processes , introducing notions like probability and probability distributions .

The normal probability plot shows the evidence of rounding and that the underlying distribution is most likely normal given how the points surround the line evenly.

A probability distribution is a statistical model that shows the possible outcomes of a particular event or course of action as well as the statistical likelihood of each event.

Animator Shuyi Chiou and the folks at CreatureCast give an adorable introduction to the central limit theorem – an important concept in probability theory that can reveal normal distributions (i ...

The cutting process is in statistical control. As a preliminary step in a capability analysis of the process, it is decided to check whether the distances are normally distributed. The following ...

For a spherically symmetric multivariate normal random sample, the asymptotic distribution of the largest interpoint Euclidean distance is derived. The number of interpoint distances exceeding a high ...
