ON QUASI MEDIANS OF A WEIBULL SAMPLE

Ahmed Zogo Memon, Abdur Razaq

Abstract


A sample quasi median may be used to estimate the median of a distribution when information on the sample median is not available. This paper expresses moments of  Quasi medians of a Weibull sample  in terms of incomplete beta functions. A comparison of  quasi medians and  sample median is made for the purpose of estimating the median of  Weibull distribution when its shape  parameter assumes various values.
