This function plots the stopping bounds \alpha_1
and \alpha_0
of an adaptive two-stage test, either onto an existing plot or into a new plot.
The function plotBounds
is invoked for its plotting effect; it returns no meaningful value.
Note that in this implementation of adaptive two-stage tests, early stopping bounds are not part of the conditional error function. Rather, they are specified separately (see also tsT
).

## Example from Bauer and Koehne (1994): full level after final stage, alpha0 = 0.5
alpha <- 0.1
alpha2 <- 0.1
alpha0 <- 0.5
alpha1 <- tsT(typ="b", a=alpha, a0=alpha0, a2=alpha2)
plotCEF(typ="b", a2=alpha2, add=FALSE)
plotBounds(alpha1, alpha0)
