Talk:Analysis of covariance

Mergers?
A variety of mergers has been proposed. Please add to the discussion at Talk:Linear regression.

Is it possible to illustrate this procedure with a picture? —Preceding unsigned comment added by 128.112.151.175 (talk) 00:46, 22 April 2008 (UTC)

This discussion is very technical for an encyclopaedia aimed at a general audience. Although the mathematical formulae are useful, some sort of explanation of the basic concepts of ANCOVA, perhaps with a few examples would make this page considerably more useful.

Figure
The model would be much easier to understand if there was a figure similar to the one here: http://www.theanalysisfactor.com/assumptions-of-ancova/. You could then put in intercepts and slopes, etc. to identify the different parts of the equation and what they are doing. Gak (talk) 11:48, 1 March 2017 (UTC)

Abbreviations use
(ab)use of the abbreviations DV, IV and CV makes this technical article practical inscrutable. Replacing these with the full terminology is preferred.

Power
The article states: ANCOVA can be used to increase statistical power. This assertion is apparently debatable: https://pdfs.semanticscholar.org/9331/9f9e57224b38219385f2acdc4b1e3cf3dbae.pdf Can someone who has more statistics expertise than I do take a look and adjudicate? — Preceding unsigned comment added by Arschein (talk • contribs) 15:29, 10 May 2018 (UTC)
