WebEstimate parameters by the method of maximum likelihood. Webas a chi-squared statistic with p 2 degrees of freedom. When the subset has only one element we usually take the square root of the Wald statistic and treat the ratio z = θˆ q j var(θˆ j) as a z-statistic (or a t-ratio). These results canbe modified by replacing the variance-covariance matrix of the mle with any consistent estimator. attack on titan art style https://staticdarkness.com

WebWe can set the sample mean equal to the expected value and solve for α to obtain the MoM estimator. Specifically, we have: Sample mean = ∑Xi/n = 21. Expected value of X = α/ (α-1) Setting these equal and solving for α, we get: 21 = α/ (α-1) α = 21/20. Therefore, the method of moments estimator for α is α = 21/20.
