Common nearly best linear estimates of location and scale parameters: normal And logistic distributions

Abstract

Common nearly best linear estimates of location and scale parameters of normal and logistic distributions, which are based on complete samples, are considered. Here the population from which the samples are drawn is either normal or logistic population or a fusion of both distributions and the estimates are computed when it is not yet known which of the two populations (between the normal and logistic) is true. The problem discussed-in this paper involves two possible population types in a given sample. Samples of sizes n = 5, 6, 8, 10 and 20 are used .to validate these estimates and a comparison of their variances is made with those of the best linear unbiased estimators (BLUEs) for normal and logistic distributions.
