title: [Statistical techniques for developing equations for impedance measurement].
abstract: The use of impedance analysis is becoming increasingly widespread as a safe, non-invasive and quick method to assess body composition. Numerous equations, based on variables derived from anthropometric variables as well as from impedance measurements analysis, have been developed to predict the alipidic mass from the resulting analysis. The most frequently used statistical method is the least squares technique. The inadequate reliability of this statistical technique is examined in this study and the use of the technique known as "ridge regression" is suggested.
