We obtain maximum likelihood estimator (MLE) and approximate maximum like-lihood estimators (AMLEs) of the scale parameter in half-logistic distribution under generalized progressive hybrid censored samples. We also obtain a Bayes estimator of the scale parameter under squared error loss function. Finally, we examine the validity of the proposed estimators using simulated data and real data. AMLEs are obtained explicitly with closed form and AMLEs are more ecient than MLE. Bayes estimator of the scale parameter is more ecient than MLE and AMLEs.
