Dear all,

I know that SIR models are not yet well documented or widely used but
I've started thinking about using them in my research - and ran into
some interpretation problems. As far as I understand from
Gianola&Sorensen 2004 SIR models should allow for estimation of Lambda
elements. However I find it difficult to translated this Lambda matrix
into the S matrix as generated by sir() in MCMCglmm. Have any of you
used these models? Or otherwise - how should  be the correct way of
specyfying a SIR model for the example in Gianola&Sorensen about
smoking and drinking (pp. 1418-1419). That would probably enlighten me
