Factor loading

Riya
Hey Listers,

Can anyone tell me the layman meaning of Factor loading ?I know a variable to be highly correlated  and high loading values to remove it. I am getting confused between correlation and factor loading.

I read somewhere "variables with higher loading values are more dominant in the factor. If two or three variable each ask something somewhat similar, and have very high loadings, this may tell you that the latent construct best reflects what these variables are getting at".

Why not considering low factor loading and high correlation to remove it ??What is the physical significance of high factor loading ??


Any help would be highly appreciated !

These should clarify.

This text (or similar) would help as well.

http://www.amazon.ca/Multivariate-Data-Analysis-Joseph-Hair/dp/0138948585

Multivariate Data Analysis
Joseph F. Hair (Author), Ronald L. Tatham (Author), Rolph E. Anderson (Author), William Black (Author)

There are newer editions but this older one, used is pretty inexpensive and the Exploratory FA section would work well in this case.
