logarithmic transformation

the conversion of raw data values into another form via the use of logarithms. In turning multiplicative relationships into additive ones and eliminating exponential trends, logarithmic transformations allow researchers to analyze data using linear models. Additionally, such transformations may be used to convert raw data into a form that more closely matches the assumptions required in particular statistical analyses, particularly that of normality.

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.
