Abstract: The article examines statistical properties of cumulative estimates of the bounds of the mathematical expectation of a discrete random variable and point estimates constructed on their basis ...

The total area under the curve must equal 1, representing the fact that the probability of some outcome occurring within the entire range is certain. \[\int_{-\infty}^{\infty}f\left(x\right)dx=1\] ...

Apply arithmetic mean of frequency distribution to find the expected value of a random variable The expected value of discrete random variable as summation of product of discrete random variable by ...

Discrete random variables take only specific, countable values. Stock prices are examples of discrete random variables due to tick sizes. Continuous random variables, like stock returns, can take any ...

Abstract: Consider a system comprising sensors that communicate with a remote estimator by way of a so-called collision channel. Each sensor observes a discrete random variable and must decide whether ...

Ever found yourself helplessly drawn to an irresistibly intriguing headline, only to be met with disappointment? If so, you might have been a victim of clickbait, the irresistible rogue of the ...

Roll a die and ask students to identify the random variable. Since a die can only take on values of 1, 2, 3, 4, 5, or 6, this is a discrete random variable. Repeat ...
