Not off hand, but that doesnt mean much. What does your data look like? Were you hoping to use informative priors?

There are lots of Bayesian nonparametrics (e.g., Bayesian quantile regression, etc.).

I have computed several Spearman's correlations already as my data is not normally distributed. I was hoping to use bayesian statistics to demonstrate the lack of relationship between my variables.

And second...yeah. Not something available in the SPSS Bayesian module at the moment. But you can do it in R.

Couple of things to keep in mind: The Spearman correlation captures a very specific type of association, monotonic. So a small rank correlation does not imply a lack of relationship. If you have two variables X and Y and define Y = X^2 you can see that the rank correlation is very small (it's 0 in the population) but the variables are strongly related.

I am not sure.

Is your sample size very large? How did you assess degree of nonnormality?
