Expected Value of a Function of a Random Variable (LOTUS)Let XX be a discrete random variable with PMF PX(x)PX(x), and let Y=g(X)Y=g(X). Suppose that we are interested in finding EYEY. One way to find EYEY is to first find the PMF of YY and then use the expectation ...
We consider the problem of numerically evaluating the expected value of a smooth bounded function of a chi-distributed random variable, divided by the square root of the number of degrees of freedom. This problem arises in the contexts of simultaneous inference, the selection and ranking of ...
be a continuous random variable with probability density function . The expected value of is provided that Roughly speaking, this integral is the limiting case of the formula for the expected value of a discrete random variable Here, is replaced by (the infinitesimal probability of ) and the int...

Answer to: Find the expected value of the function g (X) = X^2, where X is a random variable defined by the density function F_X(x) = ae^-ax u (x),...
To use the latex expected value using mathbb function, you must load amssymb package \documentclass[12pt]{article}\usepackage{amssymb}...\end{document} Next, we use\mathbbfunction. Here are five examples using LaTeX to write expected value of a random variableX: ...
There are two types of random variables; continuous and discrete. A continuous random variable is when the outcomes are continuous, not countable, and infinitely many. Continuous random variables are presented with a continuous function that is defined on the outcomes of a probabilistic even...
A continuous random variable deals with measurements with an infinite number of likely outcomes. Define random variables and learn how to compute and to interpret the expected value of a continuous random variable with the probability density function. ...
