two_source_priors_ar

Create priors for trophic position using a two source model
with \(\alpha_r\) derived from <a href="https://esajournals.onlinelibrary.wiley.com/doi/full/10.1890/0012-9658%282002%29083%5B0703%3AUSITET%5D2.0.CO%3B2">Post 2002</a>
and Heuvel et al. (2024) tools:::Rd_expr_doi("doi:10.1139/cjfas-2024-0028").

Bayesian trophic position models using 'stan' by leveraging 'brms' for
stable isotope data. Trophic position models are derived by using
equations from
Post (2002) <doi:10.1890/0012-9658(2002)083[0703:USITET]2.0.CO;2>,
Vander Zanden and Vadeboncoeur (2002) <doi:10.1890/0012-9658(2002)083[2152:FAIOBA]2.0.CO;2>,

Bayesian Trophic Position Models using 'stan'

two_source_priors_ar function

<dl><dt>bp</dt>
<dd>logical value that controls whether informed priors are
supplied to the model for \(\delta^{15}\)N baselines.
Default is <code>FALSE</code> meaning the model will
use uninformed priors, however, the supplied <code>data.frame</code> needs values
for both \(\delta^{15}\)N baseline
(<code>n1</code>, and <code>n2</code>).</dd></dl>
