This paper deals with the estimation of scale parameter for Frechet distribution with known shape. The Maximum likelihood estimation and Probability weighted moment estimation are discussed. Bayes estimator is obtained using Jeffreys’ prior under quadratic loss function, El-Sayyad’s loss function and linex loss function. Through extensive simulation study, we compared the performance of these estimators considering various sample size based on mean squared error (MSE). Key Words: Maximum likelihood estimator, Probability weighted moment estimator, Mean squared error, Loss function, Frechet distribution
1. INTRODUCTION
Frechet distribution was introduced by a French
mathematician named Maurice Frechet
(1878‐1973) who had identified before one
possible limit distribution for the largest order
statistic in 1927. The Frechet distribution has been
shown to be useful for modeling and analysis of
several extreme events ranging from accelerated
life testing to earthquakes, floods, rain fall, sea
currents and wind speeds.
Applications of the Frechet distribution in
various fields given in Harlow (2002) showed that
it is an important distribution for modeling the
statistical behavior of materials properties for a
variety of engineering applications. Nadarajah and
Kotz (2008) discussed the sociological models
based on Frechet random variables. Further,
Zaharim et al. (2009) applied Frechet distribution
for analyzing the wind speed data. Mubarak (2011)
studied the Frechet progressive type-II censored
data with binomial removals.
The Frechet distribution is a special case of the
generalized extreme value distribution. This type-II
extreme value distribution (Frechet) case is
equivalent to taking the reciprocal of values from a
standard Weibull distribution. The probability
density function (PDF) and the cumulative
distribution function (CDF) for Frechet distribution
