BCauchy {bmstdr} | R Documentation |
Cauchy prior simulation example.
Description
Cauchy prior simulation example.
Usage
BCauchy(
method = "exact",
true.theta = 1,
n = 25,
N = 10000,
rseed = 44,
tuning.sd = 1
)
Arguments
method |
Which method or package to use. Possibilities are:
|
true.theta |
True value of theta with a default value of 5. |
n |
Data sample size; defaults to 100. |
N |
is the number of Monte Carlo samples. |
rseed |
is the random number seed for drawing data samples. |
tuning.sd |
is the standard deviation of the proposal increment distribution for the random walk sampler. |
Value
A list containing the estimated posterior mean, ybar (the data mean) and the values of the numerator and the denominator integrals The routine simulates n observations from N(theta, 1). Mean of the simulated data values are returned as ybar.
Examples
BCauchy(true.theta = 1, n=25)

BCauchy(method="rejection", true.theta = 1, n=25)
BCauchy(method="independence", true.theta = 1, n=25)
BCauchy(method="randomwalk", true.theta = 1, n=25, tuning.sd =1)
