@whuber thanks, I've updated the question.

comment Model for probability of N autocorrelated events
thanks alesc, but these are quite obvious ideas. I am interested in how to parametrize the model, how to write it. That's where I am clueless. Ideas are quite clear, I need formulas now :-)

comment Suspiciously high Multivariate PSRF from gelman.diag()
thanks Matt. (2) this probably depends case by case. I think in my GLM case I can safely ignore divergence of the particular coefficients of the linear predictor if the predicted response converges.

comment Suspiciously high Multivariate PSRF from gelman.diag()
Thanks Matt! But 1) I have hundreds of models, cannot afford to visualise all chains. I definitely need some kind of statistics to do that for me 2) as for the "NOT just the ones that you are interested in", I don't agree, I do exactly this. I have hierarchical GLM model with correlated predictors, the coefficients of particular predictors sometimes do not converge. But I am interested in predicted response at given sites which converges perfectly.

Thanks Martyn. Then there is a question if this multivariate psrf shouldn't perhaps be computed differently to be useful?

comment How do I find a p-value of smooth spline / loess regression?
Greg, as I understood splines, unlike polynomials they cannot be dirrectly written as a single linear function (you would need some kind of if or step function I think, right?). So this still confuses me a bit...

comment How do I find a p-value of smooth spline / loess regression?
Thanks Greg! So the magic lm(y~bs(x,5)) is not the ordinary linear regression with a result of bs(x,5), but completely different spline regression? Maybe this is the confusing part, because I thought lm is only doing linear regression.

comment How do I find a p-value of smooth spline / loess regression?
Greg, thanks! 1) Could you please explain what is lm(y~bs(x,5)) doing and why it's not lm(y~I(bs(x,5)))? I am quite confused by this call because the result of bs(x,5) is not a variable... 2) Do I understand it correctly that the p-value I am looking for is the result of anova(fit0,fit2)?
