Centro de Documentacion de Fundación MAPFRE - Exact expressions for the bias and variance of estimators of the mean of a lognormal distribution

Notas: Sumario: Exact mathematical expressions are given for the bias and variance of the arithmetic and maximum likelihood estimators of the first moment (mean) of a lognormal distribution. On the basis of these exact expressions, and without the need for simulation, statistics on the bias and variance have been computed for a range of sample sizes and geometric standards desviations. The results reaffirm that an unbiased maximum likelihood estimator exists that has minimum varianceRegistros relacionados: En: American Industrial Hygiene Association journal. - Akron, Ohio. - Vol. 53, nº 7, July 1992 ; p. 432-435Materia / lugar / evento: Higiene industrial Contaminación atmosférica Contaminantes químicos Modelos matemáticos Modelos probabílisticos Muestreos Distribuciones de probabilidad Cálculos Control de la contaminación Otros autores: Hewett, Paul
