simple structure

in exploratory factor analysis, a set of criteria for determining the adequacy of a factor rotation solution. These criteria require that each factor show a pattern of high factor loadings on certain variables and near-zero loadings on others and that each variable load on only one factor. This minimizes the complexity of the factor solution, allows each variable to be most strongly identified with a specific factor, and increases interpretability.
