WebThe parameters of the t-distribution are referred to as the location, scale, and degrees of freedom $\nu$.The location can be estimated by the … WebMME just uses moments to fit distribution while MLE uses more information by fitting likelihood function and, I guess, it is why the former at least returns an outcome. The …
WebMethod 1 consists in using pmst with dimension d=1 . Method 2 applies integrate to the density function dst . Method 3 again uses integrate too but with a different integrand, as … WebDescription. Fit of univariate distributions to non-censored data by maximum likelihood (mle), moment matching (mme), quantile matching (qme) or maximizing goodness-of-fit estimation (mge). The latter is also known as minimizing distance estimation. Generic methods are print, plot, summary, quantile, logLik, vcov and coef.
