Minimum variance unbiased esti- mates for location and scale parameters are presented. Keywords and Phrases: Minimum variance unbiased estimates, record values, generalized extreme value distribution AMS Classification: 62G05, 60E05. 1 Introduction A random variable X is said to have the generalized extreme value (GEV) distribution if its cumulative distribution function (cdf) F (x) is of the following form F (x) = exp{−(1 − γσ −1 (x − µ)) 1/γ } (1) Where γ = 0, and x<µ + σγ −1 ,γ> 0,σ> 0 x>µ + σγ −1 ,γ< 0,σ> 0
