Abstract
This article proposed parameter Bootstrap method and generalized inference method to study the confidence interval of the comparison of variation coefficients for two normal distributions ,respec-tively .Then we compared two methods by simulation study .Parameter Bootstrap method was proposed for computing the coefficient of variations of two normal distributions .And according to generalized in-terval estimation method ,we constructed the generalized pivot quantity of the two normal distributions variation coefficient ,then two normal distribution coefficient of variation .Finally ,the simulation study for comparing two interval estimations was given .The research result indicated that the generalized in-ference method was a better interval estimation method .关键词
