hypergeometric2F1

Must be greater than b if |z| &lt; 1, and c &gt; b + a if z = 1

The default is to use the Cephes library routine. This
sometimes is unstable for large a or z near one returning Inf or negative
values. In this case, try method="Laplace", which use a Laplace
approximation for tau = exp(t/(1-t)).

method

Compute the Gaussian Hypergeometric2F1 function: 2F1(a,b,c,z) = Gamma(b-c)
Int_0^1 t^(b-1) (1 - t)^(c -b -1) (1 - t z)^(-a) dt

Package for Bayesian Variable Selection and Model Averaging
in linear models and generalized linear models using stochastic or
deterministic sampling without replacement from posterior
distributions. Prior distributions on coefficients are
from Zellner's g-prior or mixtures of g-priors
corresponding to the Zellner-Siow Cauchy Priors or the
mixture of g-priors from Liang et al (2008)
<DOI:10.1198/016214507000001337>
for linear models or mixtures of g-priors from Li and Clyde
(2019) <DOI:10.1080/01621459.2018.1469992> in generalized linear models.
Other model selection criteria include AIC, BIC and Empirical Bayes
estimates of g. Sampling probabilities may be updated based on the sampled
models using sampling w/out replacement or an efficient MCMC algorithm which
samples models using a tree structure of the model space
as an efficient hash table. See Clyde, Ghosh and Littman (2010)
<DOI:10.1198/jcgs.2010.09049> for details on the sampling algorithms.
Uniform priors over all models or beta-binomial prior distributions on
model size are allowed, and for large p truncated priors on the model
space may be used to enforce sampling models that are full rank.
The user may force variables to always be included in addition to imposing
constraints that higher order interactions are included only if their
parents are included in the model.
