WebFactor analysis is a statistical method used to describe variability among observed, correlated variables in terms of a potentially lower number of unobserved variables called factors. For example, it is possible that variations in six observed variables mainly reflect the variations in two unobserved (underlying) variables.

Communalities - IBM
A variable’s communality ranges from 0 to 1. In general, one way to think of communality is as the proportion of common variance found in a particular variable. 1. A variable that doesn’t have any unique variance at all (i.e. one with explained variancethat is 100% a result of other variables) has a communality … See more Communality (aka common variance) is intertwined with unique variance.The two types of variance make up 100% of the variable’s variance. Unique variance is in turn made up of specific variance and error variance. … See more One way to define communality is in terms of the sum of squared loadings on each principal component (McGarigal et al., 2013): Where: 1. cj= … See more Field, A.
