dieldrin

Observations below a detection limit: the dieldrin concentration (microg/kg) in roach fish (Rutilus rutilus) were measured in the Thames river near Oxford, UK
 and as a control in an upper arm, the river Ray.

datasets

Calculation of the parametric, nonparametric confidence
        intervals for the difference or ratio of location parameters
        and for the difference, ratio and odds-ratio of binomial
        proportions for comparison of independent samples. CI are not
        adjusted for multiplicity. A by statement allows calculation of
        CI separately for the levels of further factors. Please note
        that, when a (generalized) linear model can be reasonably
        assumed, there are smarter methods for CI calculation available
        than are implemented in this package!
