Web3 mrt. 2024 · Important Points: The mean value of (μ) of the probability distribution of a variate X is commonly known as expectation and it is denoted by E [X]. If f (x) is the probability density function of the variate X, then. Discrete distribution: E [ X] = ∑ i x i f ( x i) Continuous distribution: E ( X) = ∫ − ∞ ∞ x f ( x) d x. WebThe cumulative distribution function (CDF or cdf) of the random variable X has the following definition: F X ( t) = P ( X ≤ t) The cdf is discussed in the text as well as in the notes but I wanted to point out a few things about this function. The cdf is not discussed in detail until section 2.4 but I feel that introducing it earlier is better.
