linear functional relationships with heteroscedastic & non-Gaussian errors - any packages around?
...g to do this as carefully as I can. At the moment I am carrying out a Monte Carlo estimation, sampling from each PDF(x_i) and PDF(y_i) and using a orthogonal linear fit for each realisation but that is not very satisfactory as it leads to different linear relationships depending on whether I do the orhtogonal fit on x or y (as the errors on X & Y are quite different using the covariance matrix isn't all that useful either) Does anybody know of code in R to do this kind of fitting in a Bayesian framework? My concern isn't so much on getting _the_ best slope estimate but rather to have a good...
