Estimated parameter values $\mathit{\alpha }$ (blue) and $\mathit{\beta }$ (red) from a dataset consisting of the ten observations $0.01,\cdots ,0.10$ and 10 observations of $\mathit{\epsilon }$ for varying values of $\mathit{\epsilon }$. Estimation was done using MLE (dotted lines) as implemented in the R package betareg and by our (moment-based) method (solid lines).
