Yes, but ... Peer review among journals is uneven, especially for
those from private for-profit publishers. And even for top flight
journals, dealing with articles that contain analyses of large complex
data has become a considerable challenge. See e.g. "Reproducible
Publishers will publish a book written by (almost) anyone -

-- I believe this is a bit too facile. In GLM's and even in plain
(least squares) multiple regression, different residuals can have
different sd's, so that, for example, a large in magnitude residual
may seem to be "unusual" when it is not. Appropriate standardization
can be important even for "eyeballing".
