 | | In statistics, the method of moments is a method of estimation of population parameters such as mean, variance, median, etc., by equating sample moments with unobservable population moments and then solving those equations for the population moments. |
 | | The first moment, i.e., the expected value, of a random variable with this probability distribution is In probability (and especially gambling), the expected value (or (mathematical) expectation) of a random variable is the sum of the probability of each possible outcome of the experiment multiplied by its payoff (value). |
 | | Estimates by the method of moments may be used as the first approximation to the solutions of the likelihood equations, and successive improved approximations may then be found by the Newton-Raphson method. |
