Transform of random variables, a mathematical tool in probability theory and applied mathematics, plays a crucial role in analyzing the properties of random variables. It involves applying various transformations to a random variable, resulting in a new random variable with distinct characteristics. Key entities associated with the transform of random variables include the probability density function, which describes the distribution of the random variable; the moment-generating function, used to generate moments of the transformed variable; the cumulative distribution function, representing the probability of the transformed variable taking on a value less than or equal to a specified value; and the Laplace transform, useful in analyzing stability and asymptotic behavior of the transformed variable.
