Plotting contours

Plenty of packages allow you to plot contours of a "z" value; however, I wanted to be able to plot a specific density contour of a sample from a bivariate distribution over a plot that was a function of the x and y parameters. The example only plots th...

An Example for Just Another Gibbs Sampler (JAGS)

March 4, 2008

JAGS is a cross platform BUGS. Because it runs in a command mode, it is somewhat faster than other BUGS. However, I found it is a bit tacky to use it as a Windows/PC user.

Ordered logistic model with varying intercepts (random effects)
