ABSTRACT
Maximum likelihood estimates t1 and & are subsequently obtained as the simultaneous solution of these two equations. Since explicit solutions cannot be found, we must resort to iterative techniques such as Newton's method or perhap1' a "trial and error" procedure. Otherwise, we might have obtained estimates [3 and§ ofWeibull parameters as described in Section 5.3. Extreme value parameter estimates then follow from (8.2.6) as t1 = ln ~ and & = 1!3.
