Software Selegen-REML/BLUP: a useful tool for plant breeding

WebTBLUP. Trait BLUP [1,2], a large scale feature selection for genomic prediction using differential evolution; a fairly simple algorithm that assigns fitness based off an individual's GBLUP [3] accuracy. See main.py for an example of how to run. This implementation uses numpy matrices throughout. WebOn a somewhat related note, Doug Bates (the author of the R package lme4) doesn't like the term "BLUP" and uses "conditional mode" instead (see pp. 22-23 of his draft lme4 book pdf). In particular, he points out in section 1.6 that "BLUP" can only meaningfully be used for linear mixed-effects models. chonburi vessawan business co. ltd
