Too bad that can't be edited just a bit:
(1) OTS (Off the Shelf software) developed by a group having both a
long history of creating high-quality products and good QA which
doesn't need extensive from-scratch validation, only validation of
simpler routines like the computation of means, variances, linear
regression models, etc. (After all, how would anyone really validate
what, say, nlme(), yields in a complex growth-curve application, other
than one of the originators of one of the families of NLME
algorithms?)
best,
