Posterior distribution with discrete priors

Description

Computes the posterior distribution for an arbitrary one parameter distribution for a discrete prior distribution.

Usage

discrete.bayes(df,prior,y,...)

Arguments

df

name of the function defining the sampling density

prior

vector defining the prior density; names of the vector define the parameter values and entries of the vector define the prior probabilities

y

vector of data values

...

any further fixed parameter values used in the sampling density function

Value

prob

vector of posterior probabilities

pred

scalar with prior predictive probability
