Expectation of continuous random variable E(X) is the expectation value of the continuous random variableX xis the value of the continuous random variableX P(x) is the probability density function Expectation of discrete random variable E(X) is the expectation value of the continuous random varia...
This paper presents an infrastructure that can be used to formally reason about expectation properties of most of the continuous random variables in a theorem prover. Starting from the relatively complex higher-order-logic definition of expectation, based on Lebesgue integration, we formally verify key...
Conditional expectation of a continuous random variableLet us now tackle the case in which and are continuous random variables, forming a continuous random vector. The formula for the conditional mean of given involves an integral, which can be thought of as the limiting case of the summation ...
where x represents each possible value of X, and P(X = x) represents the probability of X taking the value x. For a continuous random variable, the expectation value is computed using integration instead of a summation. 3. Step-by-Step Procedure to Evaluate Expectation Value: To calculate ...
Definition 1: If a discrete random variablexhas frequency functionf(x) then theexpected valueof the functiong(x) is defined as The equivalent for a continuous random variablexis wheref(x) is the probability density function.This is the total area between the curve of the functionh(x) and...

Under the guidance of pragmatic Adaptation Theory, Chinese tourist pamphlets translation is a dynamic process in which translator makes continuous and conscious structural adaptations (both at lexical and syntactic level) and contextual adaptations (physical, mental and social worlds) to meet reading...
