pairedCI (version 0.5-4)

pairedCI-package: Confidence intervals for the ratio of locations and for the ratio of scales of two paired samples

Description

The package contains two functions: paired.Loc and paired.Scale. A parametric and nonparametric confidence interval can be computed for the ratio of locations (paired.Loc) and the ratio of scales (paired.Scale). The samples must be paired and expected means must be positive.
