Inferences for ratios of coefficients in the general linear
model
Description
With this package, it is possible to perform
(simultaneous) inferences for ratios of linear combinations of
coefficients in the general linear model. In particular, tests
and confidence interval estimations for ratios of treatment
means in the normal one-way layout and confidence interval
estimations like in (multiple) slope ratio and parallel line
assays can be carried out. Moreover, it is possible to
calculate the sample sizes required in comparisons with a
control based on relative margins. For the simple two-sample
problem, functions for a t-test for ratio-formatted hypotheses
and the corresponding Fieller-type confidence interval are
provided assuming homogeneous or heterogeneous group variances.
