mtg2 version 2.05

Section 12. H matrix added

mtg2 version 2.06

Section 9. Prediction accuracy revised

Section 6. Weighted GRM added

mtg2 version 2.08

Section 1.4. Reaction norm model

mtg2 version 2.09

Version 2.09 has fixed or improved a few things.

1. The ID order does not have to be the same between the fam file and phenotypic data file. But, the ID order between phenotypic data file and other covariate files still have to be the same.

2. Some memory allocation problems have been fixed especially for BLUP output part for the multivariate random regression model.


Version 2.17 has been optimised for the computing speed of multivariate linear mixed models (REML) that is > 10 times faster than earlier versions when fitting many levels of covariates.

Version 2.18 has now BLUP SNP (providing SNP effect, its SE, reliability, Wald test p-value, i.e. GWAS summary stats). It can supports univariate as well as multivariate models (see section 16 in the manual and example13 and 13-2).
