Centering HLM offers the options to use predictors as they are‚ or to use them after grand- or group-mean centering them. The choice of centering method is dictated by the question studied‚ and great care should be taken to select a form of centering appropriate to the model considered‚ as the interpretation of coefficients in the model is dependent on the type of centering used. We start with an example where a simple linear transformation of a predictor is used to ensure that the interpretation
