## BUGS Line Example

### Description

The Line example involves a linear regression analysis of the data points (1,1),
(2,3), (3,3), (4,3), and (5,5). The proposed Bayesian model is

*y[i] ~ N(mu[i], tau)*

*mu[i] = alpha + beta * (x[i] - mean(x[]))*

with the following priors:

*alpha ~ N(0, 0.0001)*

*beta ~ N(0, 0.0001)*

*tau ~ Gamma(0.001, 0.001)*

Two parallel chains from the MCMC sampler were generated and the output saved in the
S data frames line1 and line2.

### Usage

data(line)

### Format

The data frames line1 and line2 each containing 200 observations.
