mpp2ddSim

Utility function to format a distribution name and a vector of its parameter values
 to a <code>ddSim</code> object for use in the p/d/r/q family of functions

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>.

mpp2ddSim function

<dl><dt>distr</dt>
<dd>character string giving the name of one of the models fit by
<code>ddFit</code></dd>
<dt>parms</dt>
<dd>vector of parameters for the <code>distr</code>, or, alternatively, an array
of parameter sets. Parameterization may follow either the GLM format or the 
distribution format. For example, the xep01 model (gamma distribution) has
GLM parameters for <code>log(r)</code> and <code>r</code>, which are the coefficients of 
the polynomial in the xep01 format (namely, x * exp(b0*log(r) + b1*r)), or 
the gamma distribution parameters, <code>shape</code> and <code>rate</code>. The 
elements of parameter vector must be named. For example, 
<code>parms = c(log(r) = -0.373, r = -0.0147)</code> for the GLM format for an 
xep01 model or, equivalently, <code>parms = c(shape = 1.63, rate = 0.0147)</code> 
for the distribution format. If both formats are given, the GLM parameters 
are used and the distribution parameters ignored.</dd></dl>
