If XX is a random variable and Y=g(X)Y=g(X), then YY itself is a random variable. Thus, we can talk about its PMF, CDF, and expected value. First, note that the range of YY can be written as RY={g(x)|x∈RX}.RY={g(x)|x∈RX}....
The method of distribution functions (MODF) is a simple and powerful method to find the PDF of a variety of continuous transformations. The Change of Variable Technique (CoV-T) is a useful method to find distributions of simple continuous differentiable functions of real-valued random variables. ...
Consider the notion of a "square-law" detector: If x is an input to the detector, then y = x2 is its output or detected value. Consider next the case where x is a random variable with probability law ...Frieden, B. RoyThe University of Arizona...
A random variable is a rule that assigns a numeric value to every possible outcome in a sample space. Random variables may be discrete or continuous in nature. A random variable is discrete if it assumes only discrete values within a specified interval.
Example Let be a uniform random variable on the interval , i.e., a continuous random variable with supportand probability density functionLet where is a constant. The support of iswhere we can safely ignore the fact that , because is a zero-probability event (see Continuous random variables ...
