OddsRatio
requires a single number in the range [0,1].
plotOddsRatio
accepts more than one number on the range
[0,1] and draws confidence lines at each value.par()$oma
, needed to make room for legend.plotOddsRatio
draws a plot and invisibly returns the same
list as OddsRatio
for the first value of alpha
.
OddsRatio
returns the list:ln(psihat)
