Moment in probability
WebEdit. View history. Tools. In probability theory, the method of moments is a way of proving convergence in distribution by proving convergence of a sequence of moment sequences. [1] Suppose X is a random variable and that all of the moments. exist. Further suppose the probability distribution of X is completely determined by its moments, i.e ... Web13 apr. 2024 · This paper introduces and studies a new discrete distribution with one parameter that expands the Poisson model, discrete weighted Poisson Lerch transcendental (DWPLT) distribution. Its mathematical and statistical structure showed that some of the basic characteristics and features of the DWPLT model include probability mass …

This occurs with probability 1 / 2. In the case that X = 2, then Y = 4. This occurs with probability 1 / 4. In the case that X = 5, then Y = 25. This occurs with probability 1 / 4. So, we must have. E [ Y] = 1 ⋅ 1 2 + 4 ⋅ 1 4 + 25 ⋅ 1 4 = 31 4.
