Description Usage Arguments Details Value See Also Examples
Constructs a prior distribution for use as the argument bin_prior
in
rpost
or in binpost
. The user can choose
from a list of inbuilt priors.
1  set_bin_prior(prior = c("jeffreys", "laplace", "haldane", "beta", "mdi"), ...)

prior 
A character string giving the name of the prior for p. See Details for a list of the priors available. 
... 
Further arguments to be passed to an inbuilt prior function.
This is only relevant if 
Binomial priors. The names of the binomial priors set using
bin_prior
are:
"jeffreys"
: the Jeffreys beta(1/2, 1/2) prior.
"laplace"
: the BayesLaplace beta(1, 1) prior.
"haldane"
: the Haldane beta(0, 0) prior.
"beta"
: a beta(α, β) prior. The argument
ab
is a vector containing c
(α, β).
The default is ab = c(1, 1)
.
"mdi"
: the MDI prior
π(p) = 1.6186 p^p (1p)^(1p), 0 < p < 1.
Apart from the MDI prior these are all beta distributions.
A list of class "binprior"
. The first component is the
name of the input prior. Apart from the MDI prior this will be "beta",
in which case the other component of the list is a vector of length two
giving the corresponding values of the beta parameters.
binpost
for sampling from a binomial posterior
distribution.
1  bp < set_bin_prior(prior = "jeffreys")
