ON QUASI MEDIANS OF A WEIBULL SAMPLE

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...

Zusammenfassung: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.
