Re: [Gretl-users] maximum like. conditions

;-) This is a subtle bug (if it's a bug; I'm not sure) with an easy workaround. With the initialization scalar alpha = 0.4 scalar beta = 0 The "check" condition -- alpha>0 && beta>0 -- is violated on the first iteration. Therefore the formula for "ll" comes down to ll = NA This generates a scalar value, which is not allowed in the mle context. The fix is to initialize such that the check is satisfied on the first round, e.g. scalar beta = 0.001
