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 .

Since the point pattern is curved with slope increasing from left to right, a theoretical distribution that is skewed to the right, such as a lognormal distribution, should provide a better fit than ...

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.

You can use the RAND () function to establish probability and create a random variable with normal distribution.

Managerial accounting both uses and depends on the information probability distributions supply. A probability distribution establishes a statistical relationship between two or more variables and ...

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 ...

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 ...

Von Mises distribution: A fundamental probability distribution in circular statistics, analogous to the normal distribution in linear settings.

In this article we review two historical approximations to the Poisson and binomial cumulative distribution functions (CDFs); that is, the Wilson—Hilferty and Camp—Paulson approximations. Both of ...
