Re: st: aic bic adjusted R-squared with svy command

[John Antonakis <john.antonakis@unil.ch>]

Thompson has some nice adjectives for stepwise: “bad, evil, rotten, 
worthless, and wrong” (Thompson, 2001, p. 86); a search on the internet 
will identify other interesting adjectives like “voodoo,” and “nonesense.”

See:
Thompson, B. (2001). Significance, effect sizes, stepwise methods, and 
other issues: Strong arguments move the field. Journal of Experimental 
Education, 70(1), 80-93.

Also:
Leigh, J. P. (1988). Assessing the importance of an independent variable 
in multiple-regression--Is stepwise unwise? Journal of Clinical 
Epidemiology, 41(7), 669-677.

Best,
J.
