Examples

# NOT RUN {
data(SkiExperts)

# Visualising
with(SkiExperts,plot(paired(Actual,Imaginary),type="profile"))

# No underestimation of imaginary time for experts
with(SkiExperts,t.test(paired(Actual,Imaginary)))

# But a very interesting increase in dispersion in their
# predicted times
with(SkiExperts,Var.test(paired(Actual,Imaginary)))
