In many models, variances are assumed to be constant although this assumption is known to be unrealistic. Joint modelling of means and variances can lead to infinite probability densities which makes it a difficult problem for many learning algorithms. We show that a Bayesian variational technique which is sensitive to probability mass instead of density is able to jointly model both variances ...

Genetic evaluation by best linear unbiased prediction (BLUP) requires modeling genetic means, variances, and covariances. This paper presents theory to model means, variances, and covariances in a multibreed population, given marker and breed information, in the presence of gametic disequilibrium between the marker locus (ML) and linked quantitative trait locus (MQTL). Theory and algorithms are...

The correction is in two parts. See [3] for more information on the correction. 1. The LPEadj method discontinues the LPE practice of setting all variances below the maximum variance in the ordered distribution of variances to the maximum variance. In certain cases this practice can set many variances to the maximum and lower the performance of this algorithm. If the assumption that there are o...

The Australian dollar is considered primarily a commodity-based currency. The high level of commodity-based exports in Australia’s trade balance is given as an explanation. Accordingly changes in world commodity prices should bring commensurate changes in the value of the Australian dollar, such that changes in world commodity prices are only partially transmitted to the Australian economy and ...
