提出了一个模型和估计程序来估计育种值。衍生和实现了Cray X/MP上稀疏QR-Factorization的算法。最后,发现了一个改编的订购,与最低度订购相比,该订单具有一些优势。可以针对该算法的很大一部分明确计算有关实际问题的填充。提供了实际示例的R因子的非零结构。
A model and estimation procedure is presented to estimate breeding values. Algorithms for Sparse QR-factorization on the CRAY X/MP are derived and implemented. Finally an adapted ordering is found, which has some advantages compared with minimum degree ordering. The fill-in for practical problems could be computed explicitly for a large part of the algorithm. The nonzero structure of the R-factor of a practical example is supplied.
