Re: More Re: Partial correlations
- Will has raised the issue of partial correlations. A former colleague of
mine was fond of them as a method of removing the effect of a covariate
from a correlation. He used a "correction for attenuation" which I
understood to be a method for correcting for sample size. The source he
quoted was GH Ferguson (1976), Statistical Analysis in Psychology and
Education, 4th ed, McGraw-Hill, New York.
I've also found a couple of pages of explanation in SE Maxwell and HD
Delaney (1990), Designing Experiments and Analysing Data. A Model
Comparison Perspective, Brooks/Cole, Pacific Grove CA (p124-125).
