nonlinear transformation

a transformation of a data set that uses a function to change the linear relationship between variables. For example, a normalizing transformation creates a new set of scores that approximate a normal distribution from the original nonnormal data set, and a logarithmic transformation may be used to convert raw data into a form that more closely matches the assumptions required in particular statistical analyses. Compare linear transformation.
