likelihood, <strong>and</strong> smaller values curiously tend to be better, but not too small! Smaller values <strong>are</strong> also<br />
more efficient). Further, one should really look at the plot of the profile-likelihood to make sure that<br />
this is the case, <strong>and</strong> that resulting CIs <strong>are</strong> accurately estimated (perhaps using the locator function<br />
to be sure). Nevertheless, an attempt is made to find the limits automatically. To look at the plot<br />
along with the horizontal line, m - q, <strong>and</strong> vertical lines through the MLE (thin black dashed) <strong>and</strong> the<br />
CIs (thick dashed blue), use the verbose = TRUE argument in the call to ci. This is not an explicit<br />
argument, but available nonetheless (see examples below).<br />

Ferreira 2006).<br />
Either a numeric vector of length 3 (if only one parameter/return level is used) or a matrix. In either<br />
case, they will have class “ci”.<br />
