On nonparametric sequential point estimation of location based on general rank order statistics
Pranab Kumar Sen · 1979
A nonparametric sequential procedure for the point estimation of location of an unspecified (symmetric) distribution based on a general class of one-sample (signed) rank order statistics is considered and its asymptotic theory is developed. The asymptotic risk-efficiency of the proposed procedure is established and certain almost sure and moment convergence results on rank based estimators are studied in this context.
