In this study, we tackle the problem of estimation of stress-strength reliability R =
Pr(X < Y) based on upper record values for Exponential Power distribution. We
use the maximum likelihood and Bayes methods to estimate R. The Tierney-Kadane approximation
is used to compute the Bayes estimation of R since the Bayes estimator can
not be obtained analytically. We also derive asymptotic confidence interval based on the
asymptotic distribution of the maximum likelihood estimator of R. We consider a Monte
Carlo simulation study in order to compare the performances of the maximum likelihood
estimators and Bayes estimators according to mean square error criteria. Finally, a real
data application is presented.
