psi_extend

Extend a distance model beyond the search radius via multiplication by a fixed,
assumed constant rather than the default normalization used for extensible
models. <code>psi_extend</code> should not be used with <code>psiHat</code> objects that
were calculated with <code>extent = "full"</code>.

Fit a Poisson regression to carcass distance data and integrate over the searched area at a wind farm to estimate the fraction of carcasses falling in the searched area and format the output for use as the dwp parameter in the 'GenEst' or 'eoa' package for estimating bird and bat mortality, following Dalthorp, et al. (2024) <doi:10.3133/tm7A3>.

<dl><dt>psi</dt>
<dd><code>psiHat</code> object</dd>
<dt>fwin</dt>
<dd>fraction of carcasses assumed to lie within the search radius. If
<code>psi</code> includes <code>psiHat</code> for multiple carcass classes, <code>fwin</code>
should be either a vector with one value for each carcass class so that 
<code>length(psi) = length(fwin)</code> or a scalar (which assumes all carcasses, 
regardless of carcass class, have the same probability of landing outside the
search radius).</dd></dl>
