We consider the problem of estimating the scale parameter &beta of a rescaled F-distribution when &beta has a lower bounded constraint of the form &beta&gea, under the entropy loss function. An admissible minimax estimator of the scale parameter &beta, which is the pointwise limit of a sequence of Bayes estimators, is given. Also in the class of truncated linear estimators, the admissible estim...

Let be a random sample from a normal distribution with unknown mean and known variance The usual estimator of the mean, i.e., sample mean is the maximum likelihood estimator which under squared error loss function is minimax and admissible estimator. In many practical situations, is known in advance to lie in an interval, say for some In this case, the maximum likelihood estimator...

spinal cord injury (sci) leads to loss of nervous tissue and consequently to catastrophic neurological deficits. up to now there is no definite treatment available that restores the loss of function to a degree that an independent life can be guaranteed.this justifies the cost of research into the new modalities for a treatment of scis. in current paper, recent developments and new approaches i...
