To describe the behaviour of a discrete random variable, we use a probability distribution. A probability distribution lists all the possible values the variable can take along with the probability of ...

This curve is called the probability density function (PDF), and it describes the probability distribution of a continuous random variable, often denoted as \(X\). The total area under the curve must ...

BACKGROUND: Previous research suggests that exposures to air pollution and nonoptimal temperatures are associated with a ...

As the properties of complex random variables are most naturally specified in terms of the complex quantities directly, and given in terms of the distribution of the complex variables rather than ...

Missing income data are pervasive and consequential. From the U.S. Census’s Current Population Survey (CPS) to the EU’s SILC ...

This important study demonstrates the significance of incorporating biological constraints in training neural networks to develop models that make accurate predictions under novel conditions. By ...

This valuable study investigates how stochastic and deterministic factors are integrated during cellular decision-making, particularly in situations where cells differentiate into distinct fates ...

The Department of Mathematics and Statistics at Saint Louis University offers undergraduate options in pure mathematics, applied mathematics and statistics, as well as graduate degrees in mathematics.

Visually, the larger the variance, the "fatter" a probability distribution will be. In finance, if something like an investment has a greater variance, it may be interpreted as more risky or volatile.
