Abstract
This article discusses confidence interval for the difference of variation coefficients for lognormal distribution using the pivotal quantity, where pivotal quantity for the
variation coefficients is unavailable, but there is a parameter having pivotal quantity in coefficients of variation i.e 2 . Therefore, 2 is constructed for pivotal quantity coefficients of variation using the Generalized Pivotal Approach (GPA). This
confidence interval is shown in the term of coverage probabilities by implementing simulation studies with Matlab 7.6.0
